I applied through an employee referral. The process took 2 weeks. I interviewed at TikTok (San Jose, CA) in Mar 2024
Interview
We had a short discussion about my resume and then went through a coding interview. I was confident that I provided the best solution, but the interviewer insisted that his approach was more optimized. I even consulted with some genius friends, and they all agreed with me. However, the work-life balance at the company seems terrible based on the interview. The interview was scheduled for 1 pm, and the interviewer had just woken up because he worked from 9 am to 3 am the previous night. He had only been with TikTok for less than three months and was already responsible for interviewing candidates.
