This was my first ever interview at SAP, and think would be the last ever job application to this company, and the worst ever interview experience of my life till now. The job role requirement was mainly with the DevOps experience and understanding of the main networking concepts. There were 2 people over the call, a guy from SAP Belfast and another Indian "technical" guy from SAP Singapore, but the technical interview person's communication was really arrogant and rude. His way of asking the questions made the call very uncomfortable. As per the job description, I was prepared with my DevOps experience, networking knowledge, and some networking experience I had 2.5 years back. But the "technical" guy started asking the day to day hands-on experience questions on networking, and his way of asking the questions was more like showing off his skillsets rather than asking proper questions as described in the job description. Somehow, in an indirect way, I tried to explain this guy that i am currently working on the DevOps role, ad the questions he's asking can only be answered by a person who is working day to day in network troubleshooting, and that was the moment this guy sounded really frustrated stating "We are the hands-on experience team, we work day in and day out on networking". I think this was the moment the other guy from Belfast understood the awkward situation on the call and asked the technical guy to stop and took over the call, he was really gentle and polite, the interview continued with the behavioral, operations management questions which went really smooth. I don't think that I'll be getting any further call, but this person ruined the interview experience for me. These days, I think the most common issue with the interviews is that companies are setting a very wrong expectation with the candidate by providing a very vague and open-ended job description, and this creates a lot of problems for the candidates who are not from the same job profile. Second, and most annoying issue with technical interviews is that the technical interviewer does not understand the intention of the interview process, and they are not even ever get trained for that. I believe the intention of the interview is to find the right candidates who are capable of doing the required job, but the technical interviewers try to find the candidate who already knows what the technical interview guy is experiencing on daily basis in his project. I hope you no one else face such interviews ever in his/her life.
