Very smooth interview process. I went through a phone interview, a Codepad assessment, and then an onsite.

During the phone interview, I was asked a classic data structures problem and then a parsing question that I'd say most resembles some kind of logic puzzle. A day later, I received an invitation for the onsite.

During the onsite, I had several interviewers. Brush up on C++ before coming here; they'll ask you specifically how to do questions in C.

My first interviewer was an older gentleman who wanted me to "solve the question in 3 different ways." While I understood why he was doing this, it was frustrating because one of the ways was basically a different approach, only using different data structures. I also had to code in C here.

The next two interviewers asked about OOP, and one brought a laptop with him and had me code a simple C++ big integer class.

The last interview was with the chief architect, who asked about reversing a 64-bit integer.

Return a list of substrings of a letter in C++.

Create a BigInteger class in C++.

Reverse a 64-bit integer.
