IBM Developer interview questions

An online written, followed by telephonice interview, then a written test. Two technical rounds, a manger round with two people. The HR is super slow, the worst I have seen keep calling or they would never process it :), and even after you are selected you may not get the offer for a month, be careful.

I was asked initially the basics programming questions related to kernel lever device driver programming. Later on they shifted to asking questions pertaining to problem solving and puzzles like finding an easy way to tell whether a point lies within a n sided polygon.
