Two phone interviews:

One by a screener (general questions about education, background, etc.) and one from the manager of the facility I'd be working in.

The second interview included a long list of general questions about object-oriented programming, databases, and general computer science-related topics (i.e., "What is a...?" or "What's the difference between a ... and an ...?").

After the second phone interview, there was an on-site interview that lasted about 4 hours.

Three interviewers asked me another series of questions. They had me draw a class diagram on the whiteboard. I was asked to outline an object-oriented program (diagram an object-oriented program describing a record store), and then a detailed coding question written out on the whiteboard, where I was to convert a string of Roman numerals into an integer value. This was to be done in the language of my choice.

Finally, I was given a small program (3 files) on a computer that contained 3 errors, and I was to debug it and find the errors. This was in C#.

Coding interview: convert a string of Roman numerals into an integer value.
