I applied through a staffing agency. I interviewed at Alteos (Berlin)
Interview
An unpleasant experience, I was actively sourced for this role. At the beginning of the selection process structure was clearly defined: An introductory interview/coding assessment, a system design interview and a meeting at the office as last round. This was unfortunately untrue: after passing the first coding assessment, the second interview was a leetcode assessment where they completely ignored my solution, despite having the same big-o complexity of the one they expected. A solution taking 2*o(n) iterations is, as undisputable and objective fact, a o(n) solution. In case of further doubts, there are books about this.
My experience of half a decade in insurance was completely discarded and I was not even invited to the final round in the office. I also had to actively pursue a feedback to get the rejection.
Given the critical situation of the insurance industry, among much instability and many foreclosures and consolidations, I found dismissing the important domain experience in favor of leetcode tricks quite disturbing.
I am glad it did not play out as later I found a better role, but please, improve the interview process structure and evaluation. LLMs made leetcode assessment pratically useless since early 2022
Interview questions [1]
Question 1
Leetcode linked list question, only one solution was acceptable. Big O played no role in the solution somehow.
I applied online. The process took 4 weeks. I interviewed at Alteos (Essen, North Rhine-Westphalia) in Aug 2025
Interview
Alle waren sehr offen und ehrlich und gleichzeitig freundlich, sodass wir uns offen über die Aufgaben und Anforderungen der Tätigkeit austauschen konnten. Sehr positiv war auch, dass meine Wünsche bereits bei der Bewerbung berücksichtigt wurden, was mir die Entscheidung für eine Zusammenarbeit leicht gemacht hat.
Interview questions [1]
Question 1
die Frage, wie ich meine Arbeit in der Praxis umsetzen würde und wie mein Vorgehensplan hinsichtlich der Neukundengewinnung aussieht.
It felt like it went well, till the personal opinion of the interviewer was solely based off what he felt and nothing tangible. When i asked for reasons even though the interview seemed to go well, I got "He didn't seem like he did the job himself" Like what does that even mean. Who else would do my job for me.
