It’s 11pm. The speeches ran long, the CEO arrived late, and somebody has to decide whether the first dance moves, the party starts, or the floor gets ten more minutes. If nobody knows who that somebody is, the night decides for you.
The questions that protect you are about power, timing, backup gear, and who is allowed to make a decision at 11pm when the schedule slips. Ask those four and you’ll filter out most of the people who can’t deliver your event.
I’ve been DJing in Seoul clubs for more than twenty years, and I’ve been on both sides of this conversation: the one being hired, and the one brought in late to rescue a room where somebody else was hired badly. What follows is what I’d ask if I were booking me.

Date, Price and Genre Filter Out Almost Nobody
Almost every enquiry I receive opens with three questions: are you free on this date, what do you charge, and what kind of music do you play. Those are reasonable. They’re also nearly useless as filters, because every DJ alive can answer them in a way that sounds fine.
Availability tells you nothing about competence. Price tells you nothing until you know what’s included, which our guide to DJ costs in Seoul goes through. And “what do you play” invites a list of genres any working DJ can recite. The person who is going to let you down can answer all three perfectly.
Four Questions That Can’t Be Faked
Start with load in and setup timing. A good answer sounds like this: “For a 7pm start I am on site by 4:30, set and line checked by 5:30, and I stay quiet until doors. If your venue has a loading restriction or a lift I need to book, tell me now and I will call them this week.” A bad answer is “I will get there about an hour before.” An hour is enough time to plug in. It isn’t enough to plug in, discover the house system needs an adapter nobody mentioned, and fix it before your guests walk in.
What a Good Answer Sounds Like
And the answer that should worry you
DJ 섭외 전에 꼭 물어볼 네 가지
| Ask | Good sign | Warning |
|---|---|---|
| Setup timing | On site at 4:30 for a 7pm start, line checked by 5:30 | “About an hour before” |
| Backup | Two players plus a laptop, spare cables, music on two drives | “That has never happened to me” |
| Running order | Run sheet a week out; one named decision maker | “Just tell me when to start” |
| Venue needs | A short list: power, table, speaker spots, limiter, noise time | “Just a plug” |
The ruleSomeone who has done a hundred of these has a routine and describes it in specifics.
This kind of question works because it can’t be faked. Someone who has done a hundred of these has a routine and will describe it in specifics. Someone who hasn’t will describe it in vibes.
Next, ask what backup they carry and what happens if it fails mid set. Good: “Two players plus a laptop with the same library, a spare controller in the car, duplicate cables, and my music on two drives and offline. If a deck dies mid track, you will hear a slightly early transition and nothing else.” Bad: “That has never happened to me.” It has happened to everyone who has worked long enough. Confidence isn’t the same as redundancy, and a DJ who has never had a failure usually hasn’t had many bookings.
Third, ask who owns the running order on the night. This is the question nobody asks and everybody needs. Corporate events and weddings drift, and somebody needs the authority to move the first dance, cut a track, or hold the floor. A good answer: “Send me the run sheet a week out. I will flag where it is going to slip. On the night, name one person who can make the call, and I will take direction from them and nobody else.” “Just tell me when to start” leaves you improvising in front of your guests.
Last, ask what they need from the venue that you should confirm now. A professional will immediately hand you a short list: dedicated power, a table of a certain size, where the speakers can physically stand, whether there’s a sound limiter, and what time the noise restriction begins. An amateur will say “just a plug.” The limiter matters a lot in Seoul, and I cover why in the piece on how Korean venues run.
The Details Clients Forget Decide the Night
Power comes first, seriously. A DJ rig, a lighting rig and a coffee urn on the same circuit is how you find out what a breaker sounds like, so ask what’s already on that circuit. Then ask where the speakers physically go. Sound aimed into a low ceiling or a glass wall behaves completely differently, and the right position matters more than the size of the box.
Have the volume conversation in advance. Decide before the night whether this is a room where people talk over music or dance to it. If people are meant to dance, ask the venue whether guests are allowed to dance there; in Korea that depends on how the venue is registered, and the venue will know. Decide too whether you need an MC or just a DJ. They’re different jobs, and announcements, bilingual or otherwise, should be agreed and scripted, not sprung on the DJ at 9pm.
Language is real in Seoul. If half the room works in Korean and half in English, someone has to handle both, and it should be decided before the invitations go out. A do not play list is more useful than a request list, because every company has songs that will land badly in that particular room, and only you know them. Plan a meal and a break, too: a five hour set with no break has a fifth hour that sounds like it.
Finally, money and paperwork. Agree who is paying and when: the deposit, the balance and the overtime rate, settled before the night, not at 1am when everyone is having a good time. If you’re booking a DJ from overseas, Korea has an approval process for performances involving foreign performers. Raise it early with the promoter or venue, or ask an entertainment lawyer, rather than discovering it the week of the event.
Reassurance Without Detail Is the Warning
You’re testing whether this person has a system. Specifics, times, named equipment and a willingness to tell you something inconvenient are all good signs. Smooth reassurance with nothing underneath it is the warning, however friendly it sounds.
The single best question, if you only ask one: tell me about an event that went wrong and what you did. Anyone with real hours has a story and will tell it plainly. It’s the fastest way to find out who you’re dealing with.
Be fair to the DJ as well. A professional who flags problems early, asks for a run sheet and wants the overtime rate in writing is showing you the system working, and that system is what protects your night.
What You Get When the Answers Are Right
You get a DJ who has walked your venue, or one like it, and knows where the power is before load in day. The rig fits the room: two CDJs and a mixer on a compact stand for most events, powered speakers only when the house system won’t carry a party, all agreed and in the quote. Riders may now name the CDJ-3000X, released in September 2025 as AlphaTheta’s successor to the CDJ-3000, with built in Wi-Fi; ask which model the venue or hire company has before the night.
You get a single page running order, owned by one person, that the venue and the MC work from too. Speeches are handled properly, with the microphone, the walk up music and real silence. The do not play list is honoured without a debate, and a mixed Korean and international room is read as one room.
I work for Korean clients and international ones in equal measure, and a lot of my nights are both at once. If your room is mixed, say so early. The music and the announcements can carry two audiences comfortably, but only if somebody plans for it rather than discovering it at eight o’clock.
For most events it’s me in the booth. For larger or multi room jobs I bring in DJs I’ve worked with for years and I stay responsible for the night. You’re dealing with the person who plays, not an account manager who passes you to whoever is free. If you’re planning something in Seoul, tell me about it here. Even if I’m not the right fit for your event, I’ll tell you what to ask the person who is.
Frequently Asked Questions
What should I ask a DJ before booking them in Seoul?
The most useful questions to ask a DJ in Seoul cover load in timing, backup gear, who owns the running order on the night, and what the DJ needs from the venue. Date, price and music taste are reasonable to ask but filter out almost nobody. Price in particular means little until you know what’s included, which is explained in this guide to DJ costs in Seoul.
What backup equipment should a professional DJ have?
A professional DJ should carry real redundancy, for example two players plus a laptop with the same library, duplicate cables and music on two drives available offline. If a deck fails mid track, the audience should hear only a slightly early transition. Saying that a failure has never happened is a warning sign, because it happens to everyone who works long enough.
How early should a DJ arrive before an event?
For a 7pm start, a well prepared DJ is on site by 4:30 and set and line checked by 5:30. Arriving an hour before is enough to plug in but not enough to fix a surprise, such as a house system that needs an adapter nobody mentioned. Venue loading restrictions or lifts that need booking should be raised early so the DJ can call the venue ahead of time.
What’s the single best question to ask a DJ?
The single best question is to ask the DJ about an event that went wrong and what they did. Anyone with real hours has a story and will tell it plainly. Specific times, named equipment and a willingness to say something inconvenient are good signs, while reassurance without detail is the warning.
