IBM Software Developer interview questions

First round was an informal one. Was asked about my previous company and projects which I did in my masters and undergrad. Second round was a simple technical round. Basic oops and Java questions where asked.

Detail oriented interview with several rounds. The teschnical rounds involved coming up with several test cases around things around me like, a pen, about testing an email server etc. The other two technical rounds involved briefing me about the role and connecting it back to what I have done in the past. HR round involved a lot of aptitude and problem solving questions.
