Cadence Design Systems Software Engineer(Internship) interview questions

I applied on their website and got an email from one of their software directors within a month or so saying he wanted to schedule a phone interview. The next day we talked for about a half hour and then they offered me the job within a few days. He was very easy to talk to and made the job seem very exciting and challenging!

There were 3 interviews. First one was on my resume. Second was on C programming and a final interview was a discussion about the proposed research problem (Basically how I would approach the problem). Wherein, I prepared a presentation and spoke about it.
