I applied through a recruiter. I interviewed at Zenly (Paris) in Jan 2020
Interview
On-line interviews, then over the weekend hands on assignment, through which I could prove the range of skills I have. I was then flown in and met up with the team.
The over the weekend assignment was solving an open ended problem in a (for me) new development environment, and the challenge was how far I can solve it in a limited amount of time.
Interview questions [1]
Question 1
Zenly staff had a bunch of questions regarding how I would approach solving some of the typical problems in the relevant field, as well as some of the problems I was going to be working on if I passed the interview.
