Incaendo Technologies Java Developer interview questions

I had attended the walk-in. so I faced the bad experience from there because HR said they will call you after said to stay for some sometime. there were 6 programming questions and I have attended 5 confidently and all are right confidentiality still they said they will call me. there were two people who were holding this procedure and if they give me chance to execute during the interview I could also do that but I don't think so why they didn't call me till I had used C and Java as well using the function to show them they I know multiple languages. their expectations are very high still request to them to give a chance to the student for face to face Interview to execute the all program if they are not understanding the written code.
