# Tell me about a past project and the hardest part of tuning or fine-tuning the model.

We provide interview-preparation resources through Aced, formerly Exponent. This public question is designed for **Machine Learning Engineer** behavioral interviews and is also categorized under **Machine Learning**. Use it to practice explaining a past modeling project and the most difficult part of tuning or fine-tuning it.

## Interview experiences

**1 shared experience**

### Anthropic — Machine Learning Engineer

Reported **a year ago**. The contributor described the process as hard, thoughtful, and more advanced than a typical ML loop. Their route included:

1. A referral through someone in their network.
2. An application.
3. A recruiter screen.
4. A technical use-case screen.
5. An MLOps round.
6. A hiring-manager round.
7. A three-part final panel covering ML design, behavioral topics, and culture fit.

They said the process focused on real LLM work, including MCP and tooling, long context windows, memory, reliability, enterprise deployment, and deciding when AI is appropriate rather than plain ML. They also reported being allowed to use Anthropic's LLM in the interview system. The culture-fit round explored ethics, executive pressure, and EQ.
