Result: Failed
Difficulty: Medium to Hard
Interview Process
The interview process consisted of two rounds conducted via video. In the first round, I was asked to solve a sliding window problem and a binary tree problem. I needed to explain the solutions, including time and space complexity, but I did not have to write code for the follow-up questions.
In the second round, I was questioned about how my research direction aligned with the company’s work. I struggled to provide relevant answers. I was then asked to implement an LFU (Least Frequently Used) algorithm in C++. I spent a significant amount of time writing the code and testing it, which passed the test cases. However, I received notification three days later that I had not passed the interview.
Technical Questions
- Permutation in String
- Binary Tree Cameras
- Design an LFU Algorithm
Tips & Insights
- Be prepared to articulate how your background aligns with the company’s focus.
- Practice coding problems thoroughly, especially on data structures like trees.
- Ensure you can explain the time and space complexities of your solutions.
