J'ai postulé en ligne. Le processus a pris 2 mois. J'ai passé un entretien chez ByteDance (Seattle, WA) en févr. 2021
Entretien
1 OA
3 round of technical interviews
then HR call and offer
The OA is pretty difficult. But don't be discouraged. Even if you feel you didn't perform very well, there is still chance. The same thing goes for technical interviews. Don't give up.
Questions d'entretien [1]
Question 1
1. OA: find the closed pair of points from a set of points on a two dimensional space.
S1. Naive solution could be easy but it takes O(N^2) time and space complexity. But a divide and conquer could reduce the complexity to O(NlogN). But it's really hard to come up with.
2. Technical interview 1
Basic calculator, same as leetcode
3. Technical interview 2
Derive backpropagation formula
4. Technical interview 3
Check if a point lies inside some ranges. similiar to leetcode range module.
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.

Question 1
Technical questions related to past work experiences.
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.
