The interview was very nice and left me with good feeling. It was basic first interview about what they do and how they work. I had interview with the CTO and for a bit also with one of the cofounders. CTO seemed very pumped and promised to get back to me on Monday (the interview was on Thursday). I have never heard back from the company or from the recruiter not even a simple "Thanks but no thanks" email. I find this very unprofessional and it tells you how much they care about their new potential employees. If you make somebody to come to your location that is hard to reach by public transport it would be nice to hear at least some response even if its a No.
