I applied online. The process took 3 months. I interviewed at ByteDance (Singapore) in Jan 2022
Interview
I had 4 rounds of interviews. 3 technical + 1 last hr round.
Coding questions are relatively easy.
All technical interviews - OS, DB, network, programming language. Third round is harder compared to first 2 rounds.
Interviewers are generally quite nice.
The technical interview process is very fast. HR will ask me to proceed to the next round on the next day. However, after the third round of tech interview, I waited for a week to proceed with the HR round. After the HR round, I waited for 1 month to receive the final rejection email.

The entire interview processes was a recruiter call plus three rounds of technical interviews. Interviewers were friendly. Technical coding questions and work related questions were asked based on your past work experiences. Each interview saved time for the candidate to ask questions.

Scheduled with recruiter. Scheduled and interviewed. It was well organized. Interviewer are good. HR, manager, hiring manager. Some of the interview organized around 8pm. Some of the interview organized around 8pm.
The interview process was well-structured and relatively efficient. It typically consisted of multiple rounds:
Online assessment / initial screening: Focused on data structures and algorithms, with medium-to-hard LeetCode-style problems.
Technical interviews (2–3 rounds): Covered core computer science fundamentals (data structures, algorithms, system design basics), along with problem-solving and coding in real time. Interviewers also asked follow-up questions to evaluate depth of understanding and optimization.
Project discussion: Detailed discussion of past projects, including design decisions, trade-offs, and real-world impact.
HR / behavioral round: Focused on communication skills, teamwork, and cultural fit.
Overall, the process emphasized strong coding ability, solid fundamentals, and the ability to think clearly under pressure. Interviewers were generally professional, though the difficulty level was on the higher side, especially for algorithm questions.
