The first round of interviewing was a skill test. You could take that test in C, C++, Java, or C#.

I took the test in C. The questions were really nerdy, focusing on minute details or language features.

Prepare the K&R book well for this round.

The second round was a phone screen. A person from their Princeton, NJ R&D department called me. I guess he had no idea what position he was interviewing me for! He asked some low-level questions on OS, interrupts, etc. The questions were based on my resume and projects. There were no coding questions.

The onsite interview consisted of two rounds (after which they threw me out of their office without having met with a manager). So, if you get a chance to meet the hiring manager, that's a good sign and you are most likely through.

The questions were not difficult.

• A few conceptual questions on OO programming.
• Remove extra white spaces in a string.
• Singleton pattern implementation in C++.

I was asked to explain one of the interesting projects not listed on my resume. Both interviewers seemed too dumb to understand the idea.

I received the much-expected rejection email after a week.
