IBM Software Developer interview questions

I applied the internship position from campus career link. about 2 week after I received an email asking about my availability for on-site interview. However, almost 1 month after I did not receive any further instruction except when I tried to send an email asking about the status. Then he gave my the date and time for on-site interview. He did not get back to after few weeks after the onsite interview until I sent email asking about the progress. I did know at that time that a friend of mine has been offered with the position.

There were 4 rounds totally, phone in, 1:1, technical, HR. It was easy, not many difficult questions, all were basics. Technical test was bit difficult. Interviewers were very friendly and was mostly trying to understand my passion to the particular role I was interviewing.
