5thColumn interview questions

Got past the first round of interviews which was basically a phone screening. After this that is where the fun started. Gave me a take home project (Absolutely love it when tech companies play teacher and give take home assignments). I spent an entire afternoon working on this project only to go in the next day to have them tell me about every little detail wrong with my code from spacing to minor little things in the way I documented methods (Do I get some credit for turning in working code?). I was there for 3+ hours and I had a marathon of interviews in one afternoon. All of this for nothing.
