Brightedge Technologies Software Developer In Test interview questions

1.Contacted by the recruiter who never came back till 2 weeks of talking, and then again called back to check if I was available. 2.Once he came back a phone interview with the technical manager,generic testing questions about test-cases for a vending machine and to write normal code in java. 3.The manager mentioned an assignment to make that took a lot of my time. 4.Replied really quick ,I went for the onsite with four people. It went really well but I answered all the questions the four people had.However the architect wanted to give a solution to some problem I had no clue about and he did not seem interested in my opinion about the problem. Other 3 interviews seemed happy with my answers and answered the questions I had for them. I have never heard from them even after emailing and leaving voice mails after 1 month of the interview.I had taken a day off they should have atleast have the courtesy to sent a you are not selected email.
