After more than 2 months of hiring process and 5 interviews. One hr interview, two technical interviews, one interview with their cto and behavior interview I didn't get even a feedback after all that time being invested in their process and told that they will extend an offer soon. Sent them an email requiring a feedback and got a response that they will get back to me within a week but no hope. Despite their good reputation but i believe the attitude of not responding to shortlisted candidates is unprofessional at all.
