What it is
A single page listing several hundred problems, each tagged with the pattern it teaches and the companies known to ask it, filterable by both and by difficulty. Your completion state is saved locally.
Why it is worth bookmarking
It is the fastest tool available for the specific question of what to practise next. No login, no course, no upsell. Pick your weak pattern from the filter, get a list, work it.
The extra touch
Each problem carries a short hint about the pattern rather than the solution, which is exactly the right amount of help. A full solution ends the exercise; a nudge keeps it going.
Best for: anyone already drilling who wants a better index than the platform's own.
