6 phone interviews with folks from R&D, Quality and HR. I thought I answered the questions well enough for a face-to-face. I heard nothing back from them. Nothing from their HR, nothing from the hiring manager, and nothing from their internal recruiter. It would have been nice to get some feedback to say either I have been selected for the face-to-face or sorry, but we found better candidates. After numerous e-mails to the HR and hiring manager, I gave up.
