Interview questions [1]
Question 1
Tree node swapping. Mcqs: choose one func or one line of code that make the program work reasonably and efficiently
The interview process was smooth. OA + technical screen + HM. OA is a bit different from general leetcode but focused on testing. Technical screen is LeetCode easy/medium. HM round is chill but somehow the headcount is full so didn't get the job.
I applied through a recruiter. The process took 2 weeks. I interviewed at TikTok (Seattle, WA) in Dec 2025
