This is to bring to your notice about candidates being rejected by your company due to inconsistent evaluation methods and incompetent interviewers. I have interviewed with ServiceNow thrice in the past 2 years.
First time, I was rejected due to gaps in my knowledge. That's understood.
Second time, I was interviewed for the IoT team by a person of equal years of experience. I answered all questions correctly and had experience working with NodeRed and swarm of RPi. The reason for rejection wasn't specified. Furthermore, the interviewer wasn't able to answer my technical cross-questions about the role since, I quote, "didn't have enough experience in IoT and was new to the team"
Most recently, I was rejected over what seemed like an interview crafted to find flaws and reasons to reject me. The interviewer wasn't prepared for the interview, had no clear set of questions. He seemed to display that he hadn't thought of an evaluation criteria. He hadn't looked at my profile and was throwing words around without proper structure. Asking questions to clarify the scope and/or constraints of the question was met with resistance and irritation on his part. I agree I have gaps in knowledge, but specifically looking for those gaps by asking quirky questions about the language/framework is a deeply flawed tactic. Not to mention a quality that I would like to stay away from in teammates. Furthermore, it felt like the interviewer lacked comprehension skills and wasn't able to understand layered arguments when asked for clarifying his own questions. He seemed to be confused even when presented with options. At the end of the interview, I asked him what his background and role was like in the company. His response was "that's personal information". This is unprofessional behavior and is generally frowned upon.
I am not a mind reader. And I certainly am not a wizard in technology. But given my experience inconsistent and unprofessional methods of interviewing at ServiceNow, I can conclude that I wouldn't want to work there. I trust that you will look into the matter and have some training scheduled for future interviewers. In the very least, I expect a checklist which includes reading the candidate's resume before the interview.
