Brief introduction of what they do and some questions about my experience. The process lasted about half an hour. Got an invite to a technical task immediately after the interview.
Interview questions [1]
Question 1
How to identify and deal with overfitting and underfitting
I applied online. The process took 2 months. I interviewed at Viridien (London, England) in Aug 2021
Interview
Initial call with general 'why would you be suited for the role' questions.
After this stage, we were set a take-home coding challenge.
The challenge was ML-based: take the data they give you and build a model kind of thing.
The next stage was a technical interview. Here we are asked to prepare a technical presentation on a project we are working on, followed by a few questions on ML and the project.
Next was the live coding stage, where we are asked to solve three programming problems. The problem with this is that it is live, so the pressure was pretty intense. The coding took about 45 mins with some follow up questions.
The interviewers were super friendly and tried to make me feel as relaxed as possible.
Overall a good experience. The whole process took around two months.
