MockLabsforQuant
For Quant Finance roles

Brain-teasers, probability puzzles, mental arithmetic, at interview pace.

MockLabsforQuant trains the muscles a quant desk tests: probability under pressure, fast estimation, options intuition, and the moment of being asked one more follow-up. Voice or text. The interviewer doesn't move on until you've shown the reasoning.

What we ask

The questions you'll see, for real.

Lifted from current interview loops at top firms. Your interview partner will probe your answer until the reasoning is airtight.

Probability

I flip a fair coin until I see two heads in a row. Expected number of flips?

Brain teaser

100 prisoners, 100 boxes: what's the survival probability under the optimal strategy?

Options

A 1-month at-the-money straddle is priced at $5. What does that imply about expected move?

Market making

If a customer asks for a two-way on an illiquid bond, how wide do you quote and why?

Stochastic calc

Derive the SDE for the price of an asset under risk-neutral measure.

Estimation

How many piano tuners in London? Walk me through your assumptions.

Coverage

Built around the curriculum that actually matters.

Every pillar has a tree of subtopics, and each subtopic tracks your mastery independently. Weak areas surface on tomorrow's dashboard.
