I applied online. I interviewed at causaLens (London, England)
Interview
All interviews are quite easy. I ve talked with the recruiter and the 60-minute technical interview, with pair programming and answering technical questions. The pair programming task went really, I solved 2 problems really quick, and I answered all of the questions in the next part, expect of one.
Then I ve never heard from them again, no feedback, no replies to my follow-up emails. They GHOSTED me.
Interview questions [1]
Question 1
questions around ML topics, like what is regularisation, etc
The recruiting process consisted of three steps:
1. Interview with HR
2. Interview with Team Lead
3. Day 0
Day 0 consisted of a technical assessment (3 hours), three tech interviews (30 minutes each), and a cultural interview (30 minutes). The assessment mainly focused on coding skills and was partially related to machine learning. The interviews were generally easy, except for one interview where they delved deep into the mathematical concepts behind machine learning.

I applied online. The process took 4 weeks. I interviewed at causaLens (London, England)
Interview
The first stage was a short interview asking me to talk about my previous experience and why I was interested in working for the company. This was followed by a longer technical interview. The technical interview comprised of a short coding challenge and a general discussion about different machine learning concepts. The final stage was Day 0. This involved a 2 hour coding challenge in the office followed by three half hour interviews, one of which centred on the coding challenge.
