Machine Learning Engineer Interview Experience - London, United Kingdom
Process
The HR staff were very nice.
- HR screen (30 mins)
- Coding and ML basics interview (1 hour)
There would have been another two technical interviews and a behavioral interview. By this point, I dropped out since I received another offer. The process takes a very long time, as interviews were scheduled once a week, meaning at minimum a 5-week process.
