The interview went as expected, all well, nothing unusual.
Unfortunately, after the interview I haven't received any response. Shocking. I didn't mind that I was not successful, that was fine - they had a stronger candidate, they didn't like me, whatever. But - their lack of feedback was unexpected and there was no excuse.
This was not about my skills or the way I behaved during the interview etc. - it was about (no) common sense, (no) good manners, (not) being professional.
A simple "I am sorry but... " email (2 minutes typing) would have been enough. Well, they didn't have the time to write that email, didn't care, never mind.
That, to me, spoke volumes. I will not go back to them ever and I am glad I didn't get the job. Imagine working with these kind of people.
