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 principles, including scalability, reliability, availability, and common architectural patterns (e.g., microservices, load balancing, caching).
  4. Prepare for behavioral questions by using the STAR method (Situation, Task, Action, Result) to structure your answers.
  5. Research Avalara's business, products, and recent news to understand its market position and challenges.
  6. Prepare thoughtful questions to ask the interviewers about the role, team, and company culture.
