I applied online. I interviewed at ByteDance (Shanghai, Shanghai) in Sept 2021
Interview
-introduce yourself first
-ask the questions which is related to your resume
-let u describe the projects you did
-according to your description, ask the relevant question
-solve three algorithms, two easy and one medium from Leetcode
-based ur answer, ask you the process of solving
Interview questions [1]
Question 1
Not too many behavior questions.
Focus on coding - Dynamic Programming Medium Question
Focus on experience with your projects
For example, the Spring Boot principle in Java
How to create red-black-tree
How to select the repeated phone number from 10 Billion phone numbers (like used hashmap, bitmap, or Array).
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.
