Really disappointed. First round is a screening call with head of engineering. General questions, projects, approach... All good and relatively easy. Second round. Deep dive, explain project you have worked on in detail, etc. Golang questions, how does concurrency work Go, what is a channel, types, etc. My impression on this second round was good, the feedback during the interview was also good and the interviewer said they would contact very shortly with feedback and next steps. But I never got contacted again. I send an email asking for feedback and never got any reply. I find this really unprofessional.
