Thoughtworks Software Developer interview questions

I completed my diploma and applied for a software engineering post through a step program First there was aptitude test which included quantitative and logical related reasoning then group discussion and after that interview

They gave me a word document to submit to them for a programming test. In the end they fobbed up some excuses and said "Your code has too much function nesting" What nonsense! Nesting large blocks of code into small functions for either reuse or easy reading in short hand improves maintainability. I agree with what they said about a lack of unit tests, but having experience under my belt, I would really like to challenge them to show me in the application code that they have it ;) Another one of those interviews that is rigged cause they want to hire their own race in this case : Indian.
