Multi-stage interview process consisting of a HR stage, interview with a team manager, take-home assignment, peer review and then a culture/values interview with some peers and senior staff.
Really good and smooth experience, everyone is very warm and welcoming, and everyone seems to really love the company!

I applied online. The process took 4 weeks. I interviewed at Personio (Munich, Bavaria) in Jan 2022
Interview
Process:
1 - Interview with recruiter.
2 - Interview with Engineering Manager : Talked about prior experiences and a simple system design question (add authentication to a blog, login/logout)
3 - Home assignment : A Tree problem. It was fun but quite time consuming.
4 - Interview for reviewing the home assignment : This was separated in two, product review and code review.
NOTE: Review your code carefully before sending it, even if you miss to handle one single error, it will be a big minus.
I applied online. The process took 3 weeks. I interviewed at Personio (Berlin) in Sep 2021
Interview
Initially, HR plus Tech interview was there and it took around 60 minutes.
Their coding assignment will take more than 20 hours to even nearly complete all the checkboxes. But, if you can invest 40+ hours, you will have a better chance.

Question 1
System design
Coding assignment-related ones - do not even look at time complexities, they do not ask about time complexities or space complexities.
Focus more on the data structure side.
