Actually first I applied to another position at Atos through a recruitment agency (for PenTesting and SIEM), I even passed the technical interview. The interviewer of this interview was of a nice personality who only asked necessary questions for those positions. By that, I don't mean it was easy, he even asked me to live hack the "Hackthebox" registration!
After that interview, I was rather expecting an offer whereas suddenly I got to know by the Recruiter that due to Atos' internal issues the recrutment process had been stalled, which was actually exteremely weird because at the beginning the recruiter lady told me that Atos was looking for even 40 people! So what happened that that 40 suddenly dropped down to 0? Nobody knows.
Anyhow, Right after this info, I was directly reached out by Atos on Linkedin, this time for Senior Security Analyst position for the Incident Response team. I accepted this opportunity as well so we moved to the technical interview of this position. However, the technical interviewer of this position turned out to be just a plain man who preferred to ask technical questions about "trinkets" of IT Security, whose answers can be find at Google in less than 30 seconds. As a person who has worked as Security analyst for 3 years in total, I can easily say that none of the questions had real life applicability for an Analyst. In fact, in case someone from the Incident response needed an answer to an alike question at one of my previous workplaces, all he/she had to do was to google it! Furthermore, some of the questions were not even related to Incident Response but rather Penetration Testing!
Moreover, from the way the interview was conducted, I felt like something weird was going on. What I mean is, the interviewer didn't even bother to give a context to any of the questions and was just irresponsibly throwing out the questions randomly. For instance, instead of asking "what are the SPF records (in DNS)?", he just asked like "what is SPF?" and from there he just jumped to a totally unrelated context like "What is the difference between write 0 and write 1?", again without giving any context or explanation. The whole interview was held in this way.
The funniest and simaltaneously saddest part was, as per the non-technical part of the interview, the interviewer asked me the most cliche queston ever: "Where do you see yourself in two years?"
I am not sure whether the reason why he asked such unnessary questions was simply because of his personality or for some reason he didn't want me in his team (e.g. the position was fixed to someone else or he just prefers not to have people from certain countries in his team, who knows? ) so he decided to ask me as many trinkery details as possible within the hardest possible way of asking. Probably we will never find out!
