I had a Skype interview with a large multinational. At the end of the interview, they told me that they had positive thoughts about me and that they thought I was honest and genuine, also that they would let me know in a week whether I would have a second interview.
22 days have now passed and I haven't heard a thing. I sent an email on day 8 but never received a response. I also tried to call but got the feeling that my number was recognized and maybe they pressed the do not disturb button.
My thoughts are that company of this size with quite a large HR department should be professional enough to inform me if my application has been declined.
