Nucleus Software Exports Java Developer interview questions

It was easy. The interviewer was very cooperative and friendly. He assisted me throughout the process and provided positive feedback at the end of the interview which was around 45 mins long.

I got an email from nucleus software and my interview was scheduled on saturday. There were 3 rounds, first written, second technical, third technical+managerial. I cleared all the rounds and was told that there will be another hr round which will be telephonic but after 4-5 days they told me that there was some mistake and i didnt clear the interview although the interview was good and i answered all the questions
