Real Anthropic Machine Learning Engineer interview questions
- Why Anthropic, and why are you interested in this ML engineer prompt engineer role?
- Using only Python, clean the extracted file and do further analysis without third-party NLP packages like spaCy or Hugging Face.
- Tell me about an ethical or policy concern you raised under pressure.
- How would you think about aligning an AI model with the intended objectives and preventing misaligned or harmful behavior?
- Here is a tooling scenario where the model has to make a plan and execute a tool. How would you solve it?
- Leetcode style python coding
- Extract a clean dataset from this database using only SQL and Python.
- What compensation range are you looking for?
- Here is a messy retail sales dataset. Transform it so it is clean and ready for downstream use.
- If a customer in a regulated industry wanted to use Claude APIs, how would you design the implementation?
- In a provided Google Colab notebook, fill in the missing code to implement part of an LLM inference or output-processing step.
- Given a simple PDF-based workflow with long context windows, how would you improve reliability and performance?
- Paper-related reasearch problems
- Why did you use AI or machine learning on this problem, and how did you know it was the right use case?
- Here is a prewritten Python data pipeline for model training that is not running correctly. Find and fix the bugs.
- Tell me about a past project and the hardest part of tuning or fine-tuning the model.
- Imagine you're on a team deploying a conversational AI model across sensitive topics, and internal testing shows it gives overly confident but factually wrong answers in high-risk contexts. How would you investigate…
- How do you think about AI safety, ethics, guardrails, and governance?
- Implement an in-memory database in CodeSignal, with each round adding more functionality.
- Can you walk me through your education, courses, certifications, and any machine learning experience you have?
- Implement a streaming database with the given constraints and requirements.

“The process is kind of cold. All tasks are performed on codesignal. You are basically do the assignment by yourself with the computer and camera on.”
“The culture fit round was so deep it was almost like therapy for me. I talked about pushing back on executive pressure to launch on a timeline and raising it up to chief counsel to make sure the…”
“They gave me a simulation where I had to imagine deploying a conversational AI model that reasoned across sensitive topics, and during internal testing it started giving overly confident but…”
“The weirdest part was the final round: they dropped me into a Google Colab notebook with maybe 20 to 30 lines of skeleton Python and asked me to debug an actual LLM inference step, but you were…”
