Focused practice

Interview packs

Curated sets pulled from the full question bank — by company, by topic, or on a fixed schedule — for when you'd rather follow a plan than browse everything.

2-week sprint

A fixed practice plan, easy to hard, touching most categories in the bank — for someone with an interview coming up soon.

10 questions

Banking pack

Questions themed around Maybank, HSBC, AIA and GXBank — the joins, subqueries and window functions that come up in bank and insurer SQL screens.

6 questions

Grab pack

Grab-themed questions from the bank — rides, ads, and experimentation questions modelled on real Grab A/B tests.

3 questions

Window functions deep-dive

The window-function questions in the bank, back to back — ranking, running totals, LAG/LEAD and NTILE, the topic that trips up the most candidates.
