Interview Process
I recently had a tech phone screen interview with ByteDance for a full-time Software Development Engineer (SDE) position. The interview lasted about 45 minutes and was conducted by a senior engineer. The first coding challenge was to implement an algorithm to find the longest substring without repeating characters. The interviewer was interested in the time complexity of my solution and asked me to optimize my initial approach.
The second problem involved designing a system to track the stock price changes of a given number of companies over time. I was asked to discuss possible data structures and algorithms I would use to handle real-time updates and queries efficiently.
After the coding problems, we had a brief discussion about my previous projects and their relevance to the position at ByteDance. The interviewer was friendly, and I felt comfortable throughout the process.
