Contacted by a recruiter via LinkedIn. He described they were a hearing aid company that was integrating Life-Alert style tech to hearing aids. I thought that was innovative and wanted in on it. Was told the job was a contract job, that they were expanding their team, that this would be a long term contract. The tech interview was to be done by the Sr. Manager of tech and assisted by an engineer. It was to be an hour long. Instead, the Sr. Manager wasn't there. The engineer was accompanied by another engineer. The allotted 1 hour was summarily cut to half hour. The interview immediately jumped into OOP questions, which I knew. Followed by WPF questions, which I didn't know. The fact that anyone with programming experience can learn a framework or a stack was moot. Plus was I got to experience the legendary Minnesota Nice I've heard so much about. Totally passive-aggressive "We're not interested, but we'll keep in touch" ended the interview. Was cut off several times mid answer. Here's a tip for the guy who was rudely interrupting me. Hopefully he reads this. Hopefully if you are applying for this role, he has fixed this annoying habit, because he did it several times to me. If a candidate is rambling on, or not giving the terse answer you are fishing for, let the interviewee ramble to completion and politely say that you're in need of specific answers, and that you're very sorry, but you don't feel the candidate would be a good fit. No need to say "We'll keep in touch" when you don't intend to. No need to be rude to a person you just met. I'm not there to unclog your toilet. You were interviewing me to work with. I wouldn't want to work with someone like that. Professionalism wasn't on display. At all. I can only hope they find someone that is as equally as abrasive as that guy was. The other engineer was cordial and friendly. But not the guy running the interview. I can't stand people like that. Here's another tip. If you clearly see someone isn't answering the questions you're asking, stop the interview. No need to drag it on. WPF isn't one of those highly in demand frameworks. There are only 25 open positions on Indeed at the time of this writing in my area, and I live in one of the tech beds of the country. In comparison, there are over 500 c# open positions, over 500 C++ positions, over 600 Java positions. WPF isn't one of those frameworks that opens itself up to experimenting and playing around with. It's for Windows Desktop. Good luck finding your unicorn. I'm sure they are out there.
