Interview Practice

Prerequisites

Complete the final DSA through Interview Preparation lessons. Select only material aligned with the target role.

Tracks

• hard DSA: advanced graphs, union-find, tries, and difficult dynamic programming;
• senior machine coding: extensible interfaces, concurrency, cancellation, and observability;
• system design: multi-region, event sourcing, search, realtime, and capacity planning;
• leadership interviews: mentoring, influence without authority, strategy, and organizational failure.

Practice standard

Use timed prompts, clarify requirements, state invariants and tradeoffs aloud, implement a tested minimum, and write a retrospective. Review correctness and communication before adding complexity.

Checkpoint

Complete one role-relevant advanced round and produce evidence: solution, tests, complexity, design decisions, follow-up risks, and a revised answer.
