Quant Interview Prep You Can Put Into Practice
For quant trading, research and developer interviews
Build the skills that show up in technical interviews: probability, expected value, coding and clear explanations. Use structured lessons, practice questions and mock interviews with feedback to turn weak topics into reliable answers. Book a free quant consult to discuss your target roles and preparation.

Find Out What You Need to Practice
Take eight questions across arithmetic, probability, expected value, statistics and coding. See the solutions immediately and use your missed topics to choose your next study session.
Trading
Conditional probability, expected value, mental arithmetic and decisions under uncertainty.
Research
Probability, statistics, coding, model validation and a clear discussion of your own projects.
Development
Algorithms, data structures, testing and the systems skills named in the vacancy.
Illustrative teaching example
What Actionable Mock Feedback Looks Like
For a Bayes question, ‘work on probability’ is too broad. Useful feedback identifies the exact mistake and gives you a drill to correct it.
Observed error: treated two hypotheses as equally likely after observing evidence.
Correction: write prior × likelihood for each hypothesis, then normalize.
Next drill: solve three problems with different base rates, explain each out loud, and check the posterior sums to one.
An example of our teaching approach, not a transcript or testimonial.
When structured support is useful
Consider coaching when you can solve some problems independently but need a clearer sequence, accountability or feedback on your explanations. If you can identify gaps and review your work reliably, start with the free resources and our self-study comparison.
Book a free quant consult to discuss your preparation and program fit. Individual mock interviews and mentorship are program services; the diagnostic is available here without booking.
Match Your Practice to the Problem
You solve it, but take too long.
Separate setup time from arithmetic time. Record both, identify the slow step, and repeat a similar problem before shortening the timer.
Your answer is right but hard to follow.
Say the assumptions first, define the random variable, outline the method, then calculate. Finish with a boundary or sanity check.
You keep reading solutions.
Try each problem without notes, write down where you got stuck, and solve it again after a delay. Recognizing a solution is different from producing one.
You are preparing for the wrong round.
Match the role and assessment invitation. Trading practice emphasizes probability and decisions; research adds statistics and experiments; developer preparation needs coding and systems.
One weak topic keeps returning.
Use an error log with five categories: setup, concept, arithmetic, time and explanation. Spend the next session on the most frequent cause.
Your interview is close.
Prioritize the actual next round, a realistic timed rehearsal, and review of recurring errors. Use the two-week SIG plan or adapt the four-week study schedule.
If any of these make you say “that’s me”, then schedule a call with one of our quants here. We guarantee you there’s a better way...
How Structured Preparation Works
Measure your starting point, practice deliberately, then rehearse
01
Find Your Gaps
Start with the free eight-question diagnostic. Use the worked explanations to distinguish a missing concept from a calculation error.
02
Build a Role-Specific Routine
Combine technical lessons with independent attempts, timed sets and an error log. Trading, research and development need different balances of practice.
03
Practice With Feedback
Mock interviews test reasoning and communication together. Turn each feedback point into a specific drill and repeat it before your next rehearsal.
