Anthropic Engineering Manager, Data Infrastructure Interview Experience
Anthropic · Engineering Manager
I prepped for a normal EM system design, and then they put half an Anthropic inference design on the screen and asked me to tear it apart. That was when I realized they cared way more about design judgment and team guidance than whiteboard theatrics.
Interview process
I applied and they called me the next day, which was faster than anything else I have seen. The process was a recruiter screen, a 55 minute phone screen, and then a five-interview final loop with no take-home, all done remotely even though the role was SF-based. The most unusual parts were that the recruiter gave me actual feedback between rounds and that the EM system design was really a critique of a prebuilt Anthropic-style inference design, not a blank-sheet design.
Across the whole loop, they cared a lot more about my resume, project decisions, management style, and culture than coding or AI trivia. I ended up getting rejected, and the written feedback was that my people-management round did not show the depth they were looking for.

Recruiter screen
BehavioralIt was a pretty standard 30 minute recruiter screen, but the standout was how fast and no-ceremony it felt because they called me the day after I applied and immediately moved to scheduling the next step.

Technical round
BehavioralTechnicalPeople ManagementProject DiscussionThe 55 minute screen felt like a rapid-fire checklist with maybe 15 to 20 questions, and a couple of times I could tell they wanted me to stop once they had the signal and just move on.
Q1. Walk me through the companies and projects on your resume. Why this company, what was that project about, and what was unique about working there?
How they answeredI spent the first 15 to 20 minutes walking through the last seven years on my resume, which was three companies and the main projects at each. They were unusually well prepared and basically went line by line, so I tried to show that the experience on paper really matched an EM role like this. It felt much more thorough than the usual 'tell me about yourself' version.
Follow-up questions- Can you go deeper on each of the last three companies on your resume?
Q2. Why did you move from IC work into management, and why do you want to keep doing management?
How they answeredThey were very interested in my transition from an IC into management. I explained why I chose management, what I get out of it, and why I want to keep growing there. My big takeaway is you cannot assume they will just grant you that story because you have years of management on the resume.
Follow-up questions- What motivates you as a manager and how do you think about growing in management?
Q3. What technologies and design patterns did you use, why was the project done, and what impact did it have?
How they answeredI answered at a fairly high level on the project tech, design patterns, and choices, but the interviewer cared a lot more about why the work existed and what business or team impact it had. I was probably too long-winded here. The recruiter later told me that directly, which was actually useful feedback because it told me to lead with impact instead of talking too much about the technology.
Follow-up questions- Why was this project necessary?
- What changed because of it?

Final / onsite round
System DesignTechnicalI went in expecting a normal EM system design, but the panel already had a design on the screen and turned it into a design review around Anthropic-style inference problems instead of making me build from scratch.
Q1. Here is a design on the screen. Can you walk the end to end flow, critique it, and tell us what you would change?
How they answeredThis was a surprise. I had prepared for a blank-sheet system design, but they showed me a partially built design and asked me to review it. The problem space was very specific to AI infrastructure, around inference and batch inference, so I talked through the flow, where I would push back, and what I would change. For me it felt much more about design judgment, communication, and review skills than deep calculations or building every box myself.
Follow-up questions- What are the weak points in this design?
- How would you improve it?

Final / onsite round
ExecutionProject ManagementCross-FunctionalBehavioralThis round was basically a deep execution drill where one senior interviewer kept picking messy project situations and making me explain exactly how I handled them from a real example.
Q1. Tell me about a project where a stakeholder changed priority in the middle after work had already started. What did you do?
How they answeredHe wanted a real example, not a hypothetical. I had to talk through a project where priorities shifted after work was already underway and explain how I reset with the team, communicated the reason for the switch, and handled the tradeoffs. The whole round was less about describing a successful project and more about showing what I do when things stop going according to plan.
Follow-up questions- How did you explain the change back to the team?
- How did you get them to switch focus?
Q2. Tell me about a project where resourcing changed in the middle and timelines were affected.
How they answeredAgain he started with the theme and asked whether I had a real example, and I did. I talked through cases like losing a resource mid-project, having to rework the plan, and then going back to stakeholders and the team with a revised timeline. My prep advice here is to take every major project on your resume and think through resourcing changes, priority conflicts, design disagreements, and every other fire that could have happened.
Follow-up questions- What if someone quits halfway through?
- How do you communicate the timeline impact?
- How do you handle conflicts between teams or disagreements on the design?

Final / onsite round
Project DiscussionPresentationTechnicalThis was a project presentation round, so I had to bring a one-page PDF on a recent large project and spend the first 15 to 20 minutes walking them through it before they started drilling in.
Q1. Present a recent large project end to end.
How they answeredI came in with a PDF on one recent big project and used the first part of the round to walk through the phases, the technology, the team involved, and how we shipped it. After that, the interviewer picked one or two deep areas and drilled in. In my case, he was especially interested in GDPR data management, so I had to be ready to go much deeper on the parts of the project that looked most critical.
Follow-up questions- How many people were involved?
- What technology did you use?
- How did you ship it?
- Can we go deeper on the GDPR data management part?

Final / onsite round
BehavioralArtificial IntelligenceThis was the most unpredictable round because they started from Anthropic's published principles and then jumped between resume stories, lessons learned, hypotheticals, and ethics in a pretty free-form way.
Q1. Tell me about a bug or mistake you shipped, what the impact was, what you learned, and how you would handle that situation here.
How they answeredThey pulled examples from my resume and asked me to revisit them through an Anthropic lens. It was not a clean behavioral round with one category at a time. They would ask about something I shipped, what went wrong, what I learned, and then how I would handle the same thing here. I would absolutely study their published principles beforehand because that framing was underneath the whole conversation.
Follow-up questions- What did you learn from it?
- If the same thing happened at Anthropic, what would you do?
Q2. What would you do if there was a feature that was profitable for the company but clearly cost customers more money?
How they answeredThey did go into ethics. I said those are not everyday decisions I personally get to make alone, so I would surface the concern, talk through it with leadership, and make sure the decision was aligned at the right level instead of pretending I would unilaterally decide it. The interviewer was pretty poker-faced and open, so it felt more like they wanted to understand how I think than catch me in a right or wrong answer.

Final / onsite round
People ManagementBehavioralThis was the one round that felt a bit combative because they kept coming back to low performers and poor performance, and it felt like they were probing for a very specific management style.
Q1. How would you set the talent bar, run design reviews, and divide work when two people both want the same feature so they can still grow?
How they answeredSome of it was the usual EM material around talent bar, design reviews, and making sure stretch opportunities are allocated fairly when two people want the same work. I answered from my own management experience and tried to show how I balance delivery with growth. In hindsight, I think I probably assumed too much and did not spell out enough detail because they seemed to want very explicit examples and mechanics.
Q2. Tell me about managing poor performance and low performers.
How they answeredThis took most of the round. I answered from a more structured, process-heavy background where performance management has documentation, clear timelines, and a real chance to improve, but they kept pushing on why I would not move faster. It felt like they were looking for a much more direct, hands-on style with quicker calls, maybe six weeks instead of a long formal cycle. I had experience here, but I do not think I showed it in the way they wanted.
Follow-up questions- How quickly would you make a decision?
- What does improvement look like and how long do you give it?
Tips from the candidate
I would prep from my own resume first, not from generic industry material. For every big project, I would write out the ugly parts like priority churn, resourcing loss, design conflict, and what I actually did, because they keep pulling on those threads.
I would also over-prepare low performer stories in painful detail and study Anthropic's principles closely, because culture and management judgment show up everywhere in the process.
If you need more prep time, ask for it, but expect them to push back because they move fast.
Company culture
I saw a company that hires fast and pretty scrappy. The recruiter told me outright they do not like big ceremony, and that showed up everywhere with fast scheduling, full-cycle recruiting, and real feedback between rounds instead of radio silence.
Even for an engineering manager role, they did not seem interested in coding rounds or AI-model trivia nearly as much as leadership judgment, design review ability, concise communication, and whether I would unblock a strong technical team.
The people-management questions especially made it feel like a high-performance place that prefers quick, direct calls on poor performance rather than a slow, process-heavy approach, and their principles came up in almost every conversation.
