Choose a target level and available preparation window. Roadmaps distinguish emphasis by role while leaving room for your baseline, interview date, and company-specific process.
Roadmap matrix#
Repair language and complexity fundamentals, then build reliable coverage of common structures and core patterns before adding extensions.
Turn core knowledge into dependable implementation, testing, and small-constraint adaptation without assuming one company's level rubric.
Use diagnostics to repair graph, dynamic-programming, and core gaps, then practice combinations, alternatives, and robust testing across unseen variants.
Refresh core coding fluency, ambiguity handling, clean decomposition, and testing while reserving preparation capacity for design and leadership rounds.
Confirm the real coding format first, repair only observed gaps, and rehearse review, decomposition, and integration trade-offs without inventing a harder algorithm ladder.
Maintain coding readiness for the confirmed format or practical-code work while protecting architecture, organizational strategy, and leadership preparation.
How role focus differs#
Earlier-career plans emphasize core structures and common medium patterns. Mid-level plans add stronger graph, interval, dynamic-programming, company-targeted, and simulation work. Senior plans should still respect coding fluency while placing more attention on decomposition, tradeoffs, communication, edge cases, and testing.
