01 / 04Phase 01 of 04
Weeks 1-2: Data Structures & Algorithms fundamentals. Practice 5-10 problems per topic.
Weeks 1-2: Focus on core data structures (arrays, linked lists, trees, graphs, hash tables) and algorithms (sorting, searching, dynamic programming, graph traversal). Practice implementing these from scratch and analyze their time and space complexity. Aim for at least 5-10 problems per data structure/algorithm type.
Phase 02 of 04
Weeks 3-4: System Design concepts and practice. Focus on scalability and distributed systems.
Weeks 3-4: Dive into system design. Study concepts like scalability, availability, reliability, load balancing, caching, databases (SQL vs. NoSQL), message queues, and microservices. Work through common system design interview questions and practice drawing architecture diagrams.
Phase 03 of 04
Week 5: Behavioral questions preparation using STAR method. Reflect on past experiences.
Week 5: Prepare for behavioral questions. Use the STAR method (Situation, Task, Action, Result) to structure your answers. Reflect on past experiences related to teamwork, leadership, conflict resolution, and handling challenges. Tailor your examples to align with Postmates' values.
Phase 04 of 04
Week 6: Mock interviews and feedback. Identify and address weak areas.
Week 6: Mock interviews. Conduct mock interviews with peers or use online platforms to simulate the interview environment. Get feedback on your technical explanations, coding style, and communication. Review any weak areas identified during the mocks.
