Personio Senior Software Engineer interview questions

Really nice. Had to design a calendar app. That send out messages to a user at a desired time that app needed to be scalable. It had to be a micro service. No coding. Just explaining and drawing graphs.

The interview process per se was not that bad, even if I felt some step was redundant, with interviews that have overlapping scopes, the interviewers look all very nice and decently open to understand your thoughts (at least this was my impression), plus I found the format of the coding interview useful for assess my knowledge and understand on what your will work on (you are going to analyze the codebase of a fictional service and use the code as a starting point for discussing about architecture, optimizations and fix a bug). The thing that gave me the feeling of a huge lack of professionality is the following: After passing successfully all the stages (even the last stage looked like it went good, according to the interviewer reaction) and showing interest in getting an offer (I've reached reach out the recruiter which just ghosted me), I got an automated message to communicate that they weren't going to move on with an offer, but giving me the possibility to book a slot with the recruiter and get a feedback. I've booked a slot and waited one week, the recruiter canceled the event 30' before the start. I have invested time in this process and being rejected for no reason and without possibility to have a communication with the company. At the end I didn't feel so sad for not having received an offer
