This is only about the initial screening call from a recruiter. Based on such a start - I have decided not to proceed. The screening was mostly regular. It felt like the recruiter hadn't checked my resume at all, as after my usual intro presentation he mentioned that I might not be a match, as I was way more qualified than the job required. But the negative rating is just because of a single question asked by the recruiter later: "What object-oriented patterns have you used ... for goals like increasing performance performance ...". In my experience, questions about OOP basics could be relevant if two things are true: - If the interviewee has next to no experience, so the only thing to check is the programming basics. But the interview was for a senior engineering position. - If the interviewer knows programming basics - to understand the answer. As otherwise it is only possible to see if the answer contains some of the expected keywords. And I didn't have impression that the recruiter was knowledgeable. Also - OOP has nothing to do with performance. It could just be a tricky question - to see how an interviewee handles nonsense. But I did double-check with the recruiter and was told that it was a serious question provided by the hiring manager. I did try to explain basics of OOP, but the recruiter didn't seem to be interested in that. I also tried to explain, unsuccessfully, that OOP had nothing to do with performance. I do not expect recruiters or managers to be knowledgeable in technical stuff. But I do expect people to be aware of the limits of their knowledge. So this question meant to me both the recruiter and the hiring manager were incompetent. Not a great sign.
