I had interview in May. All communication was perfect. I've spent 3 days doing coding task in spite of interviewer said it should take only 3 hours. After that I had a discussion over go to meeting . The communication quality was bad so I understand only 70 % of our conversation and didn't enjoy conversation at all. Interviewer ask me about detail of my implementation without showing me the code. But I didn't remember all details because I did main development one week ago. After that receive rejection in email not in person.
