IBM Software Engineer interview questions

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.

Applied online. Got called up and scheduled for interview. Met with the manager and senior developer. Was asked the normal suite of textbook questions, then behavioural. Manager asked me to describe a chicken in Java. Senior developer asked 2 to 3 challenging technical questions that bridged C++ to Java, mostly design and architectural.
