I applied online. The process took 3 weeks. I interviewed at ByteDance (Shanghai, Shanghai) in Oct 2025
Interview
Three rounds about technics, and one round about basic situation. Interviewers are all friendly and technical. The technic interview didn't focus on too much about iOS development but your basic computer science knowledge.
Coding interview was a bit challenging for me. During this stage, they ask you some specific questions about software engineering and data structure. Had one big question, but was not able to make it.
