Interview Process
The interview consisted of three main rounds: a technical coding interview, a system design interview, and a behavioral interview.
The first round was a technical coding interview that lasted for about an hour. I was asked to solve two problems. The first problem involved implementing an algorithm to optimize a data structure for fast lookup, requiring a deep understanding of hash tables and their complexities. The second problem involved manipulating a binary tree and was related to finding the maximum depth of the tree.
After the coding round, I had a 30-minute system design interview, where I was asked to design a URL shortening service. This included discussing the database schema, how to handle redirection, and considerations for scalability.
Finally, I had a behavioral interview with questions revolving around teamwork, conflict resolution, and experiences from past projects. Overall, the interviewers were friendly and encouraged me to explain my thought process while solving the problems.
Technical Questions
- Binary Tree Maximum Depth (Tree, Depth-First Search)
- LRU Cache (Design, Hash Table)
Tips & Insights
Be prepared to explain your thought process clearly during technical interviews, and practice system design questions to effectively discuss architecture and scalability.
