After this the HR told that the manager of the team for which they wanted me to select has not come for the interview process that day, so, I will be having one more round with the Manager within couple of days in their office.

I waited for 2 weeks and still they havent called. I thought its better to give up. Then one morning the HR called and asked me to come to their office for the interview with the manager. Uff! A relief..

At VMWare Office, before the manager takes the interview, one more person from that team took a technical Interview.
They asked me to write the code in Java for the following questions:
1) Given an array with repeated numbers, print the frequencies of each number.
2) There are 3 kinds of balls in a big array. Red, Green, Blue color balls. Arrange them in such a way that all the red balls to the left, Green balls in the middle and Blue balls to the right of the array.
3) Modified the above question such that, the arrangement should be like, [R,G,B,R,G,B,R,G,B]. And discussed various boundary conditions.

At last, The interview with the manager:
1) Some questions on Software Development Life Cycle
Then it was a casual discussion about what their team does, and what are my roles if I get selected.
