1. Do you offer a written contract?
All of the wedding disc jockeys you interview may not have the same  standards of professionalism. A written, legal contract is one of the  first indicators of whether a DJ is professional and reliable.  Furthermore, a contract establishes the DJ’s obligation to the client  and outlines what is required for the DJ’s success, by outlining his  setup requirements and other factors related to his performance. For  this reason, a written contract is absolutely essential and any DJ not  using a written contract should not, in our opinion, be considered for a  wedding reception. 
2. Will you be the DJ at our wedding?
Often, the person you speak with is not the person who will be your  DJ on your wedding day. This is a very common practice among large  agencies. It is absolutely paramount that you have an opportunity to  interview, in person, the specific DJ that you will be working with and  determine whether you feel comfortable with them. You should also expect  that the individual DJ’s name is specified on your contract – it is the  only way you can be guaranteed his or her services at your wedding. 
3. May we meet with you in person before we sign a contract?
Many wedding DJs attempt to conduct their interviews over the  telephone and through email instead of meeting face-to-face with  prospective clients. In our experience, there are two reasons a disc  jockey would do this – either they don’t feel you are worth their time,  or they have something to hide. Some deejays are very different in  person than on the telephone and what is presented on their website, and  you should insist on meeting in face-to-face so you can judge for  yourself whether they are a good match for you and your wedding.  Your  "gut" feeling is very important in selecting the right disc jockey, and  it's practically impossible to make this evaluation unless you are  together in person. 
4. How long will you hold our date for us?
When you contact a professional disc jockey, they should be willing  to hold your date for you for a reasonable amount of time in order to  give you a chance to meet with them. They should also give you ample  time after your meeting to make a decision and give you time to  interview other DJs. Some DJs will use pressure sales tactics to “hard  close” you at your meeting, offering a special sale that ends that day,  or claiming that another couple is meeting with them for the same date –  attempting to pressure you to make a decision on the spot. Any DJ that  uses these types of tactics is unprofessional and is most likely doing  so in order to keep you from meeting other DJs (whom they know you’ll  like more than you like them). One week is a reasonable amount of time  to expect your date to be held for you following an initial meeting. At  MyDeejay, we give two weeks. 
5. Do you work exclusively for this company?
Most large agencies use independent DJ subcontractors to perform  their events. Often, these DJs work for several agencies and also accept  bookings directly. A disc jockey, or the agency through whom he is  booked, should be able to explain the DJ’s obligation to that agency and  what will happen if he leaves that agency.  Often, there is nothing  more than a verbal confirmation between the independent DJ and the  agency for each booking -- a frequent cause of problems.  If you choose a  DJ who subcontracts for several agencies and books his own events, you  need to be clear on what will happen if he is accidentally double-booked  for your wedding date, or what would happen to your event if you  contract the DJ through an agency and he decides to skip out on your  event to book something else for a higher price.  To find out whether  your DJ is available independently or through numerous agencies, try  performing a web search for their name and the word "DJ". 
6. How long have you been a DJ and how many weddings have you done?
A wedding is such an important occasion, and you don't want your DJ's  first wedding to be your own. The number of years someone has been a DJ  will give you some indication of their experience level, but some DJs  only perform for a few events (and fewer weddings) each year. A DJ with  half as many years in the industry may have many times as many weddings  under his belt, so you should also ask how many weddings the DJ has  done.  Also be sure to ask if the DJ has any formal training, either  from a DJ company or a DJ school. 
7. How many weddings do you do each year?
Just like any other profession, performing for weddings requires  one’s skills to be in top form. If a DJ performs for only a few weddings  per year, they may not be “at the top of their game” by the time your  wedding date arrives. Asking how many weddings they do per year will  give you an indication of their level of commitment to your type of  event. 
8. How many other types of events do you do per year?
Different DJs focus on different types of events – some consider  themselves a “jack of all trades” and claim expertise in all types of  events, and others are specialists. The ratio between the number of  weddings a DJ performs for and the amount of other, non-wedding events  they do will tell you where their focus lies. If you are looking for a  “low-key” wedding DJ and someone you meet with does mostly school dances  or Bar Mitzvahs, they may not be very focused on the type of  sophisticated presentation you want for your wedding. 
9. Do you perform for more than one event in a day?
Some DJs will do as many events as they possibly can, and often try  to pack their weekends with all types of DJ work. If a disc jockey has  already done an event in the afternoon before your wedding, they will  likely be physically exhausted by the latter half of your wedding, which  is exactly when they need to be the most alert and active. This is most  common at large agencies, where “weekend warriors” may perform at four  to six events over a three-day period. It is hard to believe that any DJ  could give that many couples an adequate amount of attention leading up  to, and on, their wedding day. 
10. What makes you different from your competitors?
Any professional wedding disc jockey will take pride in their work,  and be able to answer this question honestly and communicate the things  that make their services unique. Some DJs, however, will take this  opportunity to “bash” their competition and say negative things about  specific DJs or agencies. We consider this type of behavior  unprofessional (in fact, doing this is strictly forbidden for members of  the 
American Disc Jockey Association),  and is a poor reflection on them. In fact, you may want to consider  making it a point to meet any DJ that they say something bad about – DJs  that engage in this type of thing will often target the DJs they're  afraid you’ll book instead of them, and they’re probably right! 
11. Have you played at our reception site before?
Wedding experience is important, and so is familiarity with your  reception site. Every site poses different challenges – different  load-in and security procedures, different room sizes and  configurations, different acoustics, even antiquated electrical outlets  that need to be grounded manually. Hiring a DJ that is familiar with  your site will give you peace of mind that you won’t have any surprises  on your wedding day. Obviously, even the best DJs can’t have performed  at every site in the area (since there are hundreds available in any  area), but if he hasn’t been to yours, he should be willing to  adequately prepare himself prior to your event by visiting the venue  and/or speaking with the site contact and studying a floor plan. 
12. Do you act as the “emcee” and make all of the announcements?
Any professional wedding disc jockey should be comfortable with  making announcements and serving as the emcee for the wedding, it is a  standard part of the job. Some DJs, however, are not comfortable with  this and prefer to pass these duties on to someone else, such as a site  manager, who may not have a professional voice or experience speaking on  a microphone. 
13. How would you define your "style" when making announcements?
This is an extremely important question to ask because it will tell  you whether or not the DJ is the right match for your guests and the  atmosphere you’re trying to create. If you are planning an elegant,  understated wedding, then utilizing the services of a “party motivator”  or “entertainer DJ” may not be what you are looking for. If you know  your guests will need a lot of encouragement to dance, then hiring  someone who flatly refuses to make announcements probably isn’t the best  idea either. 
14. What do you do to motivate the crowd if nobody is dancing?
Different wedding disc jockeys handle this situation in very  different ways – some opt to use the microphone to try to “energize”  your guests and motivate them to dance. Others would never do something  like this and prefer to use careful song selection to ensure dance floor  success. You need to know what the DJ would do in this situation, and  determine if that is the way you would like the situation handled. 
15. What if something happens to you and you can’t make it to the wedding?
Despite meticulous planning and preparation, accidents do happen. If  the DJ is injured or otherwise unable to perform on your wedding day,  what is the backup plan? Most responsible professionals have some sort  of backup strategy should this situation ever arise, but others do not.  Often, DJs will be members of a local DJ association, and network with  other DJs who could possibly provide backup services for them in the  event of an emergency. Others take this planning more seriously and  reserve a specific DJ for every date, ensuring that backup is both  available and prepared in case of an emergency.  You need to feel  comfortable that you will still have a qualified, prepared DJ on your  wedding day, regardless of the circumstances, so the answer to this  question is very important. 
16. Will we meet again before the wedding?
Just as some deejays will prefer not to meet you when you book them,  others will prefer to conduct a “final meeting” in the weeks before your  wedding over the telephone instead of in person. While having a  face-to-face meeting for the final meeting is arguably less important  than meeting personally for an initial interview, the DJ should still be  willing to meet you in person for a second time if that's what you  prefer. 
17. Can we visit you at a performance?
Hopefully the answer to this question is “no.” We're sure that you  wouldn’t appreciate the DJ inviting prospective clients to your wedding  to see him in action. A professional DJ should be willing to take a  stand for his clients’ privacy and not offer this as a possibility.   Professional wedding DJs 
never allow this. 
18. May we speak to your references?
Speaking to a wedding DJ’s former clients is a great way to get a  feel for what it is like to work with them, and any DJ should be ready  and willing to allow you to speak with their references. He should also  be willing to contact several of these references in advance of  providing you with their information, so that they have his permission  and so you feel comfortable calling them. 
19. How do you keep your music collection up-to-date?
The majority of professional DJs subscribe to at least one of the  major music update services in order to keep their collections  up-to-date. These services provide the DJ with new, radio edited music,  often before it is even playing on the radio. Ask the DJ if they  subscribe to any of these. The most common are Promo Only, TM Century  Prime Cuts, RPM Top Hits Monthly, and ERG NuTraxx. 
20. How involved can we be in selecting music for our event?
This is an important question to ask, because some DJs prefer to  control the majority of the playlist and supplement their choices with a  small handful of your specific requests. Other disc jockeys prefer to  let the client choose the majority of the music, and then use their  expertise to make it all work. The DJ should be accommodating of your  music tastes, and you should feel comfortable with the DJ's approach and  the amount of involvement you'll be able to have in choosing the music. 
21. When do we need to submit our music requests and event details?
Most professional DJs will give you a printed song list and planning  worksheet with which to communicate the details of your event; others  will give you access to an online planning system that will guide you  throughout the entire process. You should be given ample time to make  decisions regarding your music choices and event timeline, but the DJ  should also require this information far enough in advance so that he  can adequately prepare for your event. A DJ who doesn’t ask for your  requests at least a couple of weeks before your wedding may not be able  to fulfill them. In addition, the DJ should be willing to accommodate  any later changes or additions whenever possible, rather than locking  you into a first dance song that you later regret or refusing to alter  the order of your toasts. 
22. Do you take requests from our guests?
Most DJs are happy to do so, but you should also feel reasonably  assured that any request they chose to play would not be something you  didn’t like. 
23. Can we submit a “Do Not Play” list?
Any professional DJ should be willing to honor your requests,  including your request for certain songs and genres to not be used.  Submitting a “Do Not Play” list will give a DJ a clear idea of your  limits and your expectations for their song selection at your wedding. 
24. When do you arrive to set up for our wedding?
When dealing with sub-standard DJs, there are often issues with them  being punctual and set up well in advance of your guests’ arrival.  Professional DJs will always arrive at least a full hour before their  scheduled start time in order to have adequate time to set up and get  organized before the wedding. MyDeejay's policy is to arrive at least an  hour and a half before our scheduled start time. 
25. What will you wear to our wedding?
Most wedding DJs own, and are comfortable wearing, a tuxedo when they  perform. If the groom will not be wearing a tuxedo, then it is  inappropriate for the DJ to wear a tuxedo. You should also ask what type  of tuxedo the DJ wears. Brands are unimportant (most tuxes look  practically identical), but ask about the style of vest, cummerbund, and  neckwear. Some DJs prefer a classic, understated look and others wear  flashy, shimmering or patterned vests and matching bowties. It is  important that the DJ’s “look” meets your expectations. 
26. What will you wear when you set up and break down your equipment?
This is something that is often overlooked, but can make a big  difference. If your guests arrive early for the reception or stay  afterward, will they see the DJ in a sweaty undershirt and gym shorts?  Professional disc jockeys maintain acceptable appearance standards  regardless of the situation, including setting up and breaking down  their equipment. 
27. How much of a deposit is required to secure our date?
Almost every DJ will require some sort of deposit or retainer in  order to secure your date. This is for their protection and yours. The  industry standard for deposits is 50%. Some DJs require far less, but  this is not always a good idea. If the contract language doesn’t  stipulate a specific guarantee of services and clearly outline a  cancellation policy, the DJ may only legally be responsible for  returning your deposit (sometimes as little as $25) in order to back out  of doing your wedding. While it would certainly be considered  unprofessional, there certainly isn’t any financial incentive for the DJ  if he’s only forced to pay a small fee for backing out on you. 
28. What is included in the cost of my event?
DJs use vastly different systems when pricing their services. Most  DJs price their services a la carte, charging an hourly rate and adding  charges for any additional equipment needed. Others choose to use a  flat-rate pricing system and make their packages all-inclusive. You need  to be clear about what a DJ is offering for the price they’ve quoted  you, so you can compare their package to those of the other DJs you are  interviewing. 
29. How much would you charge for overtime?
Hopefully your DJ will do such a wonderful job at your wedding that  you’d like to keep dancing! Be sure that the DJ’s contract outlines a  specific rate for additional time at the end of the night, whether it is  a set price or a pro-rated amount based on the original price. 
30. What do you require from us?
Every DJ will require a few things that you’ll need to provide them  in order to be successful. The most common are adequate shelter,  electricity, and a table for their equipment. Make sure that you  understand exactly what the DJ needs from you so you can communicate  those needs to your reception site and caterer. 
31. Do you require a meal?
Some DJs require that they receive a meal at the wedding, and some  even demand that they be fed the same food as your guests. Others do not  require a meal at all, or simply accept one if you happen to offer.  Again, be sure you know what the DJ’s requirements are so you can plan  accordingly. 
32. Are you insured?
It is absolutely essential that any DJ you consider carries a full  liability insurance policy. They are fairly inexpensive (less than $250  per year in some cases), so being uninsured is inexcusable. Some  reception sites have even taken the step of requiring all vendors  working at their facility to provide proof of insurance before the  wedding. Liability insurance protects you and the reception site in the  unlikely event that your DJ injures one of your guests or burns your  reception site to the ground. 
33. Do you take any breaks?
One of the major advantages to using a DJ instead of a band is that a  DJ does not need to take breaks, outside of using the restroom and  possibly eating a meal quickly in another room (if this is what your  site contact or caterer requires). In any case, the DJ should assure you  that there will be no break in the music at any point during the  reception. 
34. What is your policy on alcohol or smoking during the wedding?
A professional DJ will never consume alcohol or take cigarette breaks  during your wedding. If you interview a DJ and he tells you he needs a  few drinks to “loosen up” while working, you should probably look for a  DJ with higher standards of professionalism. 
35. What kind of equipment do you use?
Any DJ you consider should be proud of his sound system, and should  be using professional-grade equipment. Most DJs understand that you are  very unlikely to have a working knowledge of  professional DJ equipment,  but he should be able to describe his sound system to you. You should  not hear very many “home audio” brands in what he describes – the top  brands for DJ equipment are Pioneer, Denon, PCDJ, Traktor, Serato,  Electro-Voice (EV), JBL, Bose, Mackie, RANE, QSC, and Shure. 
36. Do you bring backup equipment with you to the wedding?
Even the very best and most well-maintained equipment will  malfunction at some point. Your DJ needs to be prepared in case this  happens at your wedding. The only way you will not suffer a setback on  your special day is if the DJ brings a full second sound system with  them to each and every wedding. Having backup equipment in a warehouse  50 miles from your reception site won’t do much good if there is no  music at your wedding for an hour. 
37. Do you have a wireless microphone?
Every professional wedding DJ should offer a wireless microphone to  be used for your guests’ toasts, blessing, and any other speeches that  need to be made. The industry standard for wireless microphones is  Shure, and most professional DJs use Shure wireless technology. 
38. Do you have a “light show”?
Some DJs also offer “party lights,” either as part of their package  or as an additional service they can provide. You should find out  whether the DJ plans on setting up lights for the dance floor, and  whether this matches your preferences. Also, if you do desire a light  show, you may want to ask how this will affect the aesthetics of your  reception (in other words, how bulky/cumbersome the setup is) and the  quality of your photographs or video. In our experience, most weddings  do not need (and practically none of our clients even ask for) a light  show. 
39. Do you set up a sign or banner with your equipment?
Shameless self-promotion sometimes rears its ugly head at wedding  receptions in the form of a sign or banner advertising the DJ’s company  name and contact information. These items inevitably find their way into  your wedding pictures and video, and ruin what is an otherwise  commercial-free event. This practice is repulsive and completely  unprofessional, and we believe that any DJ that does this should never  be hired for a wedding. 
40. Do you belong to any professional associations or trade groups?
If a DJ is serious about his craft and interested in becoming a  better performer, they will often join a local DJ association or trade  group. These are opportunities for DJs to interact with one another,  share ideas, and network with other DJs who might be able to help them  should they ever have an emergency. While membership in one of these  organizations is not a guarantee of that DJ’s talent level, it does at  least show a willingness to grow and improve and become a better DJ.
