Preparation

How to prepare.

Tips

  1. Review fundamental data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, graph traversal).
  2. Practice coding problems on platforms like LeetCode, HackerRank, or AlgoExpert, focusing on medium to hard difficulty.
  3. Study system design concepts: scalability, availability, consistency, load balancing, caching, databases (SQL vs. NoSQL), message queues.
  4. Prepare for behavioral questions using the STAR method (Situation, Task, Action, Result).
  5. Understand common software development methodologies (Agile, Scrum).
  6. Research Target's mission, values, and recent news.
  7. Prepare questions to ask the interviewer about the role, team, and company culture.

Data Structures and Algorithms

Weeks 1-2: DSA fundamentals and practice (2-3 problems/day).

Weeks 1-2: Focus on Data Structures and Algorithms. Cover arrays, linked lists, stacks, queues, trees (binary trees, BSTs, AVL trees), graphs, hash tables. Practice common algorithms like sorting (quicksort, mergesort), searching (binary search), dynamic programming, and graph traversal (BFS, DFS). Aim to solve at least 2-3 problems per day.
