Expert Tips
- Practice LeetCode easy and medium problems before the OA — focus on arrays, strings, trees, and graphs.
- For system design, use the RESHADED framework: Requirements, Estimation, Storage, High-level design, APIs, Detailed design, Evaluation.
- Prepare 3–4 STAR stories covering: a challenge you solved, a time you worked in a team, a project you owned end-to-end.
- After every coding solution, proactively state the time and space complexity — interviewers expect it.
- Study common CS fundamentals: process vs thread, TCP vs UDP, REST vs GraphQL, SQL indexing, CAP theorem.
