Domande di colloquio presso Compatio

They conducted interview process that took almost a month and all through the process the HR was very positive that I would be hired. And when almost everything was ok the verge of finalising they send me an email saying your technical knowledge is not aligned with our needs ! And when I call them up for feedback’s they neither accept the calls nor reply to mails . Ghosting the candidate after investing so much of time and efforts is not a professional approach.
