Thoughtworks Software Developer interview questions

Had applied online and got a call from the recruiter saying to brief about the interview process. Had to code the solution for one of the two questions and send the code for the same in approximately three days. Worked on the code to incorporate OOPs concepts and more, however after submitting the solution, never heard from the recruiter. Also, when I sent an email asking for comments on the code, I got no reply. I hope that the recruiters do give feedback when considerable amount is spent on our side to code and get to know the company. One of my other friends also had a similar experience and when he called the recruiter, he was informed that the position was for Chennai and since he wasn't open for Chennai location; inspite of his code being good, he won't be considered. I hope Thoughtsworks recruiters show some level of professionalism in providing feedback.
