ByteDance Software Engineer Interview Questions
215+ ByteDance Software Engineer interview questions drawn from real candidate reports. Sources include 1Point3Acres, Blind, Glassdoor, Reddit, and LeetCode. Questions span every stage of the ByteDance Software Engineer loop: OA, phone screen, system design, behavioral, and onsite coding.
What to Expect in the ByteDance Software Engineer Interview
The ByteDance Software Engineer interview process typically runs 4 to 6 rounds depending on seniority level. Based on candidate reports in the LeakCode database, the loop usually includes a resume review, an online assessment or coding phone screen, one or more technical rounds, a system design round (for senior and above), and a behavioral or values round.
Difficulty skews toward medium and hard LeetCode-style problems in the coding rounds. System design questions test breadth (component selection, scaling, trade-off reasoning) more than deep implementation. Behavioral questions are tied to the company's stated values and principles.

bytedance tiktok software engineer tech phone screens: two attempts and feedback
今年面了两次TikTok,来说说体验 第一次是面Tech Lead Content E-Commerce,本人在世界最大E-Commerce公司混了14年,以为这个比较match. 第一轮国人小哥,小哥技术可以,纯聊我的项目(个人觉得还比较有意思),没出任何题目。一周后收到pass通知。 第二轮国人大哥,大哥技术不错,又纯聊我的项目,没出任何题目。又一周后收到pass通知。 第三轮HR说是Hire Manager面试,于是准备了一些Behavior的问题,结果又来了一国人小哥,这小哥技术感觉一般,感觉是能说不会做的那种,不是hire manager,又是纯聊做过的项目,没聊任何Behavioral问题。小哥现场让我找一个线上的tool来画一下做过的东西,完全没有准备,现场找的tool完全不熟悉,小哥又没有很多我做的东西的domain knowledge,于是沟通效率很差,没聊到很多项目重点。又一周多收到fail通知。 总结失败原因:1. 沟通效率差没聊到点上,只要面试官没听到重点肯定是candidate的问题 2. 他们更倾向于在加州 3. 有更好的candidate已经面过...

书接上文https://www.1point3acres.com/bbs/thread-1175978-1-1.html,上轮面试居然给我过了,再次感谢面试官手下留情。 这轮主要是system design + coding。 system design: 设计role based relational database,user, role, permission, resource, 他们的关系应该是什么。太久没用relation db了,完全忘了多对多应该怎么设计,关联表都没写,全靠面试官提醒。 coding: lowest common ancestor,给了parent指针,没刷到,o(1)不知道怎么做,也是面试官提醒才写出来。 面完一周没消息,应该是没了,也没啥好问的,面的太差。

以下内容需要积分高于 200 您已经可以浏览 感觉被老哥故意刁难了 用java面试,具体是什么题目不太记得了,非常长,需要理解一会儿的题目,有点类似task scheduler,反正可以用priorityQueue。因为是java,三bro在最后followup说这个还能用treemap,但我说这个会需要sort by value, not by key,他就说对的,这个在java怎么写?我就懵了,他就开始在IDE里面自己操作,然后发现自己也没法完全写出来,这部分就草草结束了。没想到还有下一part,是一道SQL题(requirement里也没有提到SQL?)太久没手搓了,磕磕绊绊写出来了。貌似接下来还有一个简短的类似ood的环节,给一个scenario写一个solution,真的记不太清楚了 一整个大放飞

hr linkedin找过来随便面面,本来说的是2道leetcode结果挖了20分钟简历。主要问题是hardest project,遇到什么edge case,深挖这个项目的详细细节 之后做了一道lc437变种, tree从binary变成了N ary Tree。其他不变 之前没有刷到过,我给的思路是dfs 然后sliding window去查看是否有targetsum,但面试官必须要求我想出最优解O N才行,好久没有刷题早就忘了prefix sum这个知识点,导致最后也没做出来 现在tt怎么变成用飞书面试了,连代码都要在飞书上写。。 move on 了 求米

How to Prepare for the ByteDance Software Engineer Interview
Use the LeakCode question database as your primary research tool. Filter by role (Software Engineer), then by round type to focus your prep on the specific stages in your upcoming loop. Sort by recency to see what 2026 candidates actually faced.
- Start with questions from the last 12 months. Interview processes change and recent data is the strongest signal.
- Cross-reference questions that appear in multiple sources (1p3a, Blind, Glassdoor). Multi-source confirmation means a question has stronger recurrence probability.
- For system design rounds: focus on the question patterns, not individual questions. The same design principles recur across many prompts.
- For behavioral rounds: map your experiences to the company's stated values before the interview. Most behavioral questions at top companies are derivatives of a small set of core leadership competencies.
