Live subscription product; site blocks automated fetch, so pricing was read from a 2026 Wayback Machine copy of the pricing page. source
A question-bank subscription for quant trader and researcher interviews, with probability, brainteaser and mental-math drills tagged by firm, at about $20 to $35 a month. It suits candidates who already have the math and need volume and timing practice in the month before onsites. Before paying for a year, confirm the free tier does not already cover the topics you are weak on.

Interview-prep depth
3 / 5
Pricing and playlist pages: question bank with company tags and timed mental-math drills; nothing on behavioral or system design.
Job support: structured. The product is interview practice: hundreds of premium questions with solutions and hints, filtering by the company that asked them, playlists and a mental-math timer. No human mock interviews.
Whatever the program covers, the interview itself is free to prepare for here: coding patterns, system design, practice prompts, company guides.
What a careful reader should know
Often described in r/quant as the LeetCode equivalent for quant trader and researcher screens. Company tags are user-reported, not verified by the firms. The live site returned 403 to automated fetches on the check date; figures come from an archived copy and should be rechecked at purchase.
Third-party signals: Reddit sentiment positive. Graduation-time star ratings are collected by the schools; weigh them accordingly.
