Are these real interview questions, or made-up practice problems?
Real ones. Every question comes from actual quant interviews and OAs, sourced from
real debriefs and people taking the assessments. Firms do rotate their questions
over time, so the point is not to memorise the exact prompt you will get. It is to
drill enough of the real patterns so that whatever they throw at you, you have seen
enough similar questions that you are fast and calm.
Is it firm-specific? Can I filter by the company I'm interviewing with?
Yes. You pick the firm and practise the questions that firm has actually asked. We
tag 38 firms, so if you have a Jane Street or Optiver or DRW loop coming up, you can
go straight at their style instead of grinding generic problems.
How is this different from Green Book / QuantGuide / QuantQuestions / TraderMath?
Green Book is great and you should do it, but it is a general textbook, not
firm-specific and not a live, growing bank. The paid sites each do one slice: some
are mostly mental-math OA drills, some have a few hundred questions. This is the
biggest bank of the lot, it is firm-taggable, and it is the cheapest of them. If you
are only going to pay for one thing, the honest pitch is that this covers the most
ground for the least money.
Has anyone actually got an offer off the back of this?
Yes. People who prepped on these questions have gone on to trade at IMC, Da Vinci, DV
Trading, Optiver, Maven, Wincent and others. These are real offers real students have
received.
When should I start prepping? I don't have an interview yet.
Start now. Realistically you need one to two months of steady practice to be sharp,
not two weeks. The single most common mistake I see is people who wait until they
receive an interview invite and then start prepping, by which point it is already
too late. If you are a first or second year, being ready before you apply is the
whole edge.
Do the questions get outdated since firms change them?
Firms rotate, yes, and that is exactly why volume matters and why we keep adding.
You are not buying a fixed list to memorise. You are building the pattern
recognition and speed that survive a rotation, plus we keep the bank current.
Is it worth it for the price?
It is £20/month, less than two meals out, and one
offer pays for it several thousand times over. First-subscription nerves are normal,
but the risk is not the price, it is spending the summer on random PDFs and walking
into a Jane Street final under-prepared. Plus, you can cancel anytime.
Can I cancel anytime?
Yes. You will also keep access to the questions and answers until the end of your
active subscription period.
I've never done quant prep before. Will I even understand the questions, or do I need to be advanced already?
You are the person who needs this most. Easy questions let you get an understanding
and practise the most important core topics (expected values, probabilities,
combinatorics, recurrence relations, game theory) that come up most often. Then you
move on to mediums with better intuition, and grind baby grind.
