I applied through a recruiter. The process took 1 week. I interviewed at ByteDance (Beijing, Beijing) in Aug 2023
Interview
Two rounds of virtual 1-to-1 interview. Each round lasts 1 hour. The second round kind of repeating the first round so I suspect the interviewer didn't read the report of first round.
Interview questions [1]
Question 1
Self introduction resume-related questions: Tell your understanding to Transformer. What is GPT? (GPT-2 is enough) What should you do if sequence length is very long. Leetcode questions: longest common subsequence, construct rand(5) using rand(7).
Questions about projects and then 2 leetcode questions. Be prepared to discuss in detail any tech stack, models, approaches, etc mentioned on your resume. Lots of questions about math implementation and architecture of LLMs
Hackerrank online assessment. 5 questions intotal, 2 MCQs and 3 coding questions. First two are leetcode easy to medium, and the last one is leetcode hard. They do test you on linux stuff even if you are applying for a machine learning position.
