I applied online. I interviewed at ByteDance in Dec 2020
Interview
4 rounds of tech interviews and a research presentation (1 hour). You will be told whether there is a next round only after passing a round of interview. Very time-consuming. The company needs to improve their hiring processes.
Interview questions [1]
Question 1
Mainly about research projects. Some coding problems.
- easy leet code style code test
- ask about research experience
- talk a lot about view of current tech and future improvement
- ask the implementation of some basic algorithms
I applied through an employee referral. The process took 4 weeks. I interviewed at ByteDance (San Jose, CA) in Apr 2025
Interview
The interview process is very smooth, about 1-2 rounds per week with a total of 4 rounds. The first 3 are technical rounds that include both project deep-dive and leetcode questions. The last 1 is a hiring manager round and the HM introduced projects on the team.
