I had two Skype interviews of approximately one hour each. I spent a lot of time preparing the interviews for an intern position in Berlin for nothing, unfortunately... At first, the interviewers I talked to seemed very interested in my profile during our discussions. However, they changed the interview dates and timing several times just before the schedule interviews. Moreover, they asked me to do a PowerPoint presentation of a case study that they sent me to assess my skills. I spent hours doing it but I never get any feedback from them at all although I asked politely for one, neither on my assessment nor on why they decided not to select me. They said they would let me know, but they never did. If you ask someone to do that much work for just an interview, you should be able to spend 5 minutes of your time for at least a feedback. It’s a matter of respect ...

Very unprofessional. When you finish an interview saying "I have a good feeling, we will contact you next week", please do, it's called respect. I've sent an email one week after, no answer. It kind of says a lot, I'll never try again. I am very happy they didn't contact me back at the end when I read all the bad reviews on glassdoor, doesn't seem such a nice place to work at
