Anthropic Software Engineer Interview Questions
97+ Anthropic Software Engineer interview questions drawn from real candidate reports. Sources include 1Point3Acres, Blind, Glassdoor, Reddit, and LeetCode. Questions span every stage of the Anthropic Software Engineer loop: OA, phone screen, system design, behavioral, and onsite coding.
What to Expect in the Anthropic Software Engineer Interview
The Anthropic 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.

anthropic software engineer tech phone screen: task management oa
题目是Task management, 第一，二问很基础，就不赘述了 第三问：可以给task设置一个ttl, task要在到这个ttl的时候，自动被删除 第四问：你需要保存用户的在某个时刻的task list, 然后可以返回该用户任何时刻的task list 时间很紧，疯狂码代码，跪求能进下一轮~~~~ 1, FYI, 一些个人的感觉，我感觉test case测试的不是很严谨，主要还是测了happy path. 所以你如果有一些小的bug, 可能不会被test case发现。 2, 自己准备的OA的感觉来看，想好数据结构的方式，比逻辑更重要。因为逻辑都没有特别难，但是如果你数据结构选的不好了，第一，你容易在第三四问发现需要重构代码，第二或者你的一些实现需要写更多的代码，容易出bug

anthropic software engineer onsite interview experience and tips
内容其实没啥，标准流程电面coding Q1, HM chat (20 minutes, team match?) VO coding Q2, sys design Q1 然后是hiring manager, culture, technical deepdive 总体来说，coding就是要快，天下武功唯快不破，当然适当的显示你的能力，比如文件去重，md5和sha系列的hash有什么区别，应该用哪个之类的。 system design 我觉得简单了……我觉得我的系统没搞得特别好，但是面试官（我校友！）看起来挺满意，可能是有些地方我回答的比较好, 比如如何bring up GPU machines faster 之类的 那些软的面试反而是难的，因为没有标准答案。尽量表达出真实的自我吧，做过的事情你就自然的能讲好，没做过的编出来他们也不会信 猎头说feedback really positive，等过reference check和offer了 :)

anthropic technical phone screen: llm agent coding interview
今天约了人类学电面，但是portal里没有给coding的题号，只有coding interview。然后prompt如下，貌似是build一个LLM agent。请问有面过这题的么？貌似还没在论坛里见过 This interview will test writing code with LLMs as a building block, and prompting to create an agent.

How to Prepare for the Anthropic 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.
