Workflow
A simple loop that compounds.
This site is designed for daily reps: learn a pattern, solve problems, review mistakes, and turn it into a story you can explain clearly.
- Warm up with one easy/medium problem in your weakest topic.
- Do a timed medium/hard and write a short post-mortem.
- Spend 10 minutes on system design (trade-offs, not templates).
- Practice one behavioral answer out loud — concise and specific.
Quality bar
Aim for clarity: readable code, clean invariants, and explanations that make a recruiter feel safe hiring you.
