IBM Software Engineer interview questions

Java:What is Garbage Collection? C++:static Database:What is Descartes? Algorithm:How many sorting algorithms are there? Software Test: software test classification?

Given considerable flexibility in choosing an interview date and time. Technical phone interview covered basic programming concepts and some problem solving. Interview was relaxed, with the interviewer being very supportive. Notified quickly that I wasn't selected for the position. When I requested feedback, I was contacted immediately and received valuable feedback for future interviews, as well as being urged to try again.
