IMC Trading Behavioral Interview Questions
- Know that IMC reads fit through a recorded video and recruiter call, with no onsite behavioral round
- Prepare the questions people get, from "why IMC" to "what do you know about trading"
- Speak to IMC's six values in its own words; it grades fit and way of working, with no value scorecard
IMC's behavioral read is light, and it lands in two specific places: a one-way recorded video interview early in the process, and a short recruiter or HR call. On top of that, motivation surfaces from the very first CV screen, where a recruiter tends to ask what you already know about trading. The signal is real, but it is gathered on camera and over the phone, not across a panel of interviewers with a scored rubric.
That changes how you prepare. Almost nobody rehearses for the video round, and it's mechanically unforgiving. You get a few seconds to read each prompt, then a short window to answer to a camera, with no interviewer to read or steer. The questions themselves are not exotic, they are the standard early-career set, but delivering a tight, specific answer under a countdown to a blank lens is its own skill. Practice that format directly, and treat "why IMC" as the question the whole thing keeps circling back to.
The IMC Trading angleThe IMC Trading behavioral questions people actually get
The behavioral prompts cluster into a small, consistent set, most of them delivered through the one-way video interview. The list below is what recurs across candidate reports. Prepare a genuine, specific story for each, tight enough to deliver in under two minutes, because that is roughly the ceiling the video gives you.
Motivation and fit
3 questionsThe load-bearing thread. IMC wants to see that you are here for this firm and this kind of work, and that any offer at any trading shop will not do. The recruiter often opens the whole process by asking what you know about trading, so a vague answer here stalls you before the technical rounds even start.
Why did you choose IMC?
The near-universal opener. Name what IMC actually is, a proprietary trading firm and market maker, and tie it to something concrete you want to work on. Prestige and comp make weak reasons.
What do you know about trading?
Asked as early as the CV screen. You do not need a quant's depth for the software stream, but you should be able to say what a market maker does in plain terms and why low-latency software is core to it.
Tell me about yourself.
The warm-up. Keep it to a crisp arc that lands on why the systems-and-performance side of engineering is the work you want.
Self-awareness
2 questionsIMC's culture is flat and collaborative with responsibility handed over early, so it reads for people who know themselves honestly and work well alongside others. These are the classic self-description prompts, and the tell is specificity over polish.
How do your friends describe you?
A recurring video prompt. Pick two or three real traits and back each with a one-line example rather than reciting adjectives.
What are your strengths and weaknesses?
For the weakness, name a real one and the concrete thing you are doing about it. A humble-brag disguised as a weakness reads as evasive.
Problem-solving and resilience
2 questionsIMC assesses how you work through hard problems and how you recover when things go wrong, which mirrors the working-session round the rest of the loop is built around. Keep these stories concrete and quantified where you can.
Tell me about the hardest engineering problem you have had to solve.
Choose a problem with real technical depth you can explain, and spend your airtime on your reasoning and the trade-offs, and keep the backstory short.
Describe a time you performed poorly and then bounced back.
A recurring prompt. Own the dip honestly, then show the specific correction and what changed afterwards. The recovery is the part being graded.
Where the fit read actually happens
Because there is no isolated behavioral onsite, the useful mental model is a signal gathered in a few specific spots rather than probed across a panel. The exact shape flexes by role, region, and intake, so treat the layout below as a typical pattern rather than a fixed template.
- CV / recruiter screen: Motivation first. A short call on your background where the recruiter typically asks what you know about trading and why IMC. This is where the motivation read lands first, so it is not a throwaway warm-up.
- One-way recorded video: ~10 questions. The main behavioral instrument. Around ten questions mixing behavioral prompts with technical agree-or-disagree statements. You get roughly 15 seconds to read each one, then a short window, about 45 seconds to 2 minutes, to answer to camera, with an option to stop early.
- Recruiter / HR call: ~15 minutes. A brief call on motivation and logistics, location preferences, timelines, and comp expectations. Lighter than a full behavioral round, but still a place to sound genuinely interested rather than transactional.
The one-way video is the round to rehearse out loud, because its format trips prepared candidates more than its questions do. There is no interviewer to nod, follow up, or pull you back on track, and the countdown is unforgiving. Practice answering each of the questions above to a camera or a phone, timed, until you can open with the point and finish inside two minutes without rambling. Getting the delivery mechanical frees you to actually be specific.
IMC's six core values and culture
IMC publishes six values on its own culture page. The firm describes itself as flat and non-hierarchical, with responsibility handed to people from day one, a high-performance environment that is also genuinely collaborative, and a workforce spanning around 70 nationalities. You do not get scored value by value, but knowing the language lets you frame your stories in terms IMC recognizes.
- Value 1: Dare to continuously innovate. A market maker competes on staying ahead technically. Stories where you tried a better approach rather than the safe default land here.
- Value 2: Champion the best ideas. The best idea wins on its merits, regardless of who raised it. Show that you argue from reasoning and change your mind when the evidence does.
- Value 3: Collaborate to succeed. The flagship round literally simulates solving a problem alongside colleagues, so collaboration is graded behavior.
- Value 4: Take responsibility. Responsibility from day one is a stated part of the culture. Ownership stories, including ones that went wrong and how you carried them, fit directly.
- Value 5: Keep both feet on the ground. A pragmatic, low-ego register. Quantify honestly and avoid overclaiming, which reads as grounded rather than polished.
- Value 6: Build for our future. Durable, long-horizon thinking over quick wins. Stories about fixes and systems that outlast the immediate task fit this one.
The IMC Trading angleAnswering "why IMC"
Treat this as two questions stacked together: why this kind of firm, and why IMC specifically. The credible version shows you understand what IMC is: a private, Amsterdam-founded proprietary trading firm and market maker that quotes on more than 100 exchanges. Software engineering there means low-latency systems on the critical path of trading. Name that concretely. Then connect it to the work you actually want, the performance and systems side of engineering, and to something you have built that points the same direction.
The failure modes are predictable. Leading with reputation or compensation, or giving an answer that would fit any hedge fund or any big-tech employer equally, reads as someone who has not thought about fit. So does confusing the two IMC streams: the software-engineering track you are interviewing for is a different process from the trader and quant track, which runs neuroscience-based games and trading simulations. Knowing that distinction, and being clear you want the engineering work, is itself a small signal that you did the homework.
A behavioral answer, worked
Take the bounce-back prompt, one of the recurring video questions, and work it into a tight answer you could deliver inside the two-minute window.
The dip, owned plainly. "In my first months owning a data pipeline, I shipped a change that passed my own tests but slowed the nightly batch enough that it started missing its window twice a week. I had optimized for the happy path and never load-tested against a full day of records. That was on me."
The correction, specific. "I stopped adding features and spent a week profiling. The cost was a per-row lookup I was doing inside a loop; I moved it to a single batched query and added a realistic load test to the pipeline's checks. The batch went from missing its window to finishing with roughly forty percent headroom."
What changed durably. "The bigger lesson was that I had been measuring correctness but not performance under real volume. I made a load test on production-scale data part of how I sign off any pipeline change now, and it caught a separate regression a few months later before it ever shipped." That answer is short, honest about the failure, quantified, and it ends on a durable change rather than a one-off patch, which is exactly what the prompt is reading for.
What clears the bar, and what stalls
The same story can land either way depending on how you tell it, and on the video there is no interviewer to rescue a weak answer. The split below is what the fit read is watching for.
The answer that clears the bar
- "Why IMC" names what the firm actually is. A proprietary trading firm and market maker where low-latency software is on the critical path, tied to the systems work you want and something you built.
- Tight, timed delivery. You open with the point and finish inside two minutes, because the video gives you no room to ramble your way to it.
- Quantified, honest stories. Concrete numbers and a real weakness or failure, which reads as "keep both feet on the ground" rather than rehearsed.
- A clear "I" over the load-bearing beats. Your reasoning, your fix, your change, so it is obvious what you did versus what the team did.
- Recovery stories that end on a durable change. The process or habit that stops the failure recurring, beyond the immediate patch.
The answer that stalls
- A "why IMC" that fits any employer. Leading with prestige or comp, or an answer that would suit any hedge fund or any big-tech firm equally.
- Rambling past the clock. Burying the point in backstory until the recording cuts you off mid-thought.
- Vague, un-quantified impact. "It got a lot faster" with no baseline and no number, which the grounded, evidence-first culture hears as hand-waving.
- A story told entirely in "we." No clear personal contribution, so nobody can tell what you actually did.
- A weakness that is a humble-brag. "I care too much" reads as evasive; a real weakness with a real correction reads as self-aware.
Common questions
What behavioral questions does IMC Trading ask?
The recurring set is the standard early-career one. Why did you choose IMC, and what do you know about trading? Tell me about yourself, how your friends describe you, and your strengths and weaknesses. Then the hardest engineering problem you've solved, and a time you performed poorly and bounced back. Most are delivered through a one-way recorded video, alongside technical agree-or-disagree statements you explain.
Does IMC have a dedicated behavioral round?
Not a heavyweight standalone one. IMC gathers behavioral signal through the one-way recorded video interview and the recruiter or HR call, and motivation comes up from the first CV screen. There is no panel behavioral round with a scored value-by-value rubric the way some FAANG loops run one.
What are IMC's values?
IMC publishes six: dare to continuously innovate, champion the best ideas, collaborate to succeed, take responsibility, keep both feet on the ground, and build for our future. The culture is described as flat, non-hierarchical, and high-performance but collaborative, with responsibility handed over early. You are read for fit against these rather than scored one by one.
How do I answer "why IMC"?
Show you know what IMC is: a private proprietary trading firm and market maker where engineering means low-latency systems on the trading path. Connect that to the performance-and-systems work you want and to something you've built. Avoid answers that lead with prestige or comp, or that would fit any employer, and be clear you want the software track rather than the separate trader stream.
Key Takeaways
- ✓IMC has no heavyweight standalone behavioral onsite. The fit read is gathered through a one-way recorded video interview and a short recruiter or HR call, with motivation probed from the first CV screen.
- ✓The recurring questions are the standard early-career set. Expect why IMC, what you know about trading, tell me about yourself, and how friends describe you. Strengths and weaknesses, the hardest problem you solved and a bounce-back-from-poor-performance story round it out.
- ✓The one-way video is the round to rehearse, because its format is what trips people: seconds to read, under two minutes to answer to a camera with no interviewer. It also mixes in technical agree-or-disagree statements, roughly three behavioral to seven technical.
- ✓IMC states six values and reads fit and way of working without a scored value-by-value scorecard, so do not invent a leadership-principles gate. Use the language to shape genuine, quantified stories, and answer "why IMC" with specificity about what the firm actually does.
