Machine Learning Scientist Interview Experience - London, United Kingdom
Process
2.5hr HackerRank OA.
Two weeks later, I was invited to the final round. This round consisted of three interviews:
- Behavioral
- Technical/ML theory
- Reviewing the HackerRank submission
These interviews were scheduled with about two days' notice.
Questions
Typical behavioral questions:
- Think about how you work and what you can bring to the company.
Standard textbook ML knowledge and some practical scenarios.
For the final interview on the HackerRank submission, the interviewer had prepared some questions based on my solution. My advice would be to preempt questions and think beyond your submission.
