three technical interviews focused on problem-solving, coding, and core computer science fundamentals. Depending on the role, there may also be discussions around past research or project experience, system design, or domain-specific knowledge
I applied online. I interviewed at ByteDance in Dec 2020
Interview
After submitting the resume there were two rounds of interviews. I was asked questions about resume and prior experience and then a leetcode medium coding problem. After you pass one round, you are moved to the next round.
Round of introductions. First discussion about research with a focus on current project and past experience, then worked on leetcode-style coding questions with subquestions that talk a bit about system design.
Interview questions [1]
Question 1
How to implement a hash-based aggregation in Python? (Extend to out of memory, extend to accelerators)
Three rounds. The first two are research+coding. The third one is casual talk with hiring managers. Technical questions are not that easy but not hard either. It takes about 20 minutes to answer the questions.
