QUANT INTERVIEW PROCESS: EVERY STAGE EXPLAINED
Most early-career quant processes move through five filters: resume, online assessment, an initial conversation, technical interviews, and a final round. The order changes; what each stage is trying to learn is much more stable.
UPDATED 2026-10-29 · 12 MIN READ · BY THE VARIANCE EDITORIAL TEAM
Checked 29 October 2026. We used IMC and Jane Street's published process descriptions to build this map. Your rounds and waiting times may look different.
The first surprise is that two candidates at the same firm can have quite different processes. A trader might start with timed arithmetic; a researcher might get a coding assessment or a conversation about a project. Use the map below to find your next step, then check the invitation for the details that actually apply to you.
The process at a glance
| Stage | What it tests | Your job |
|---|---|---|
| Resume screen | Role fit, evidence of quantitative work, communication | Make the relevant evidence easy to find |
| Online assessment | Speed, accuracy, probability, logic, or coding | Follow the invitation and manage the clock |
| Phone or Zoom screen | Motivation, communication, logistics, sometimes technical basics | Explain why this role and think aloud |
| Technical rounds | Reasoning depth in the skills used by the role | Show the method, not just the result |
| Final round | Consistency across several interviewers and unfamiliar problems | Reset between interviews and stay collaborative |
What firms officially confirm
IMC publishes one of the clearest early-career examples. Its APAC guide describes an online assessment, an initial behavioural call by phone or Zoom, a first technical interview, and a final assessment day. Its general recruitment page is more cautious: assessment and interview details vary by role.
Jane Street describes phone interviews at the start of its trading process and in-person interviews at the final stage. It also says the conversations do not require prior finance knowledge. These are useful reference points, not an industry template.
1. Resume screen
The resume screen asks a narrow question: is there enough evidence to justify the next, expensive step? A trader resume should make numerical decision-making and competitive work visible. A research resume needs hypotheses, methods, and results. A developer resume needs code that ran under real constraints.
See the full quant resume screen guide. Do not mistake school name for the whole decision. A clear project with a defensible result gives a reviewer something to evaluate; a list of advanced course names often does not.
2. Online assessment
The OA is not one exam. Trading screens can emphasise fast arithmetic, sequences, probability, and decisions under time pressure. Research and developer screens can add statistics or coding. Some firms use several assessments. Some do not use one for a particular role at all.
Read what a quant OA is and how to prepare, then use the rules in your own invitation. A reported 80-in-8 or 50-in-5 format is evidence about one test, role, and cycle. It is not a universal cutoff.
3. Recruiter, phone, or Zoom screen
This can be a friendly logistics call, a behavioural interview, a light technical screen, or a mixture. IMC officially describes its first call after the assessment as behavioural. Jane Street's trading phone interviews are conducted by quantitative traders and are technical conversations. The meeting title matters less than the interviewer and agenda in the invitation.
Prepare a two-minute account of why the role fits you, two examples of learning under pressure, and a clean setup for thinking aloud. The phone and Zoom guide separates recruiter calls from technical screens.
4. Technical interviews
Technical rounds are where role differences become decisive. Quant traders are commonly asked to reason about probability, expected value, market making, and risk. Researchers should expect statistics, modelling, coding, and questions about previous work. Developers should expect algorithms, systems, debugging, and language fundamentals.
Use our technical interview question map and the role-specific quant trader preparation guide. State assumptions before calculating. If the interviewer changes the problem, explain what changes in your model.
5. Final round or assessment day
A final round is usually several evaluations rather than one harder question. You may meet traders, researchers, engineers, and recruiters; complete technical stations; or work through a game or case. The aim is to see whether the strengths from earlier rounds survive different contexts and interviewers.
Read the final round and Superday guide for pacing, resets, and debriefs. One poor answer does not justify mentally ending the day.
What candidate reports can and cannot tell you
An individual report can give you an idea of what one person faced, but it cannot establish the sequence or timeline for your application. IMC's published guidance provides one example; your invitation is the better guide to your own next step.
Use reports to identify skills worth practising. Do not infer a firm's cutoff, your result, or a rejection from somebody else's timeline.
Four misconceptions
- Every firm follows the same funnel. They do not, even within one firm.
- A perfect OA guarantees an interview. Firms can review the OA with the resume and hiring needs.
- A recruiter call cannot be technical. Sometimes it is; confirm the agenda.
- The final round is only a harder technical. It often tests consistency, communication, and recovery across a sequence.

Frequently asked questions
What are the stages of a quant interview process?
A common early-career sequence is resume screen, online assessment, recruiter or behavioural call, one or more technical interviews, and a final interview day. It is not a universal template. Firms change the order by role, office, and recruiting cycle, and some skip the OA or recruiter call.
How long does the quant interview process take?
There is no reliable industry-wide timeline. A process can move in days or take several weeks because firms review in batches, coordinate interviewers, and run different calendars by region. Use a deadline or response window only when the firm or recruiter gives you one.
Do all quant jobs have an online assessment?
No. Online assessments are common in graduate and internship hiring, but experienced roles and some research or developer processes can begin with a recruiter or technical interview. Even within one firm, assessments vary by role and office.
Are quant interviews mostly math?
Not always. Trading interviews often emphasise probability, expected value, mental arithmetic, and decisions under uncertainty. Research roles add statistics, modelling, and research discussion. Developer roles lean more heavily on coding, algorithms, and systems. Behavioural evidence matters across all three.
