Thoughtworks Software Engineer interview questions

1. Phone call with talent scout. 2. Phone call with software engineer, mostly non-technical. 3. Take-home project. 3 options to choose from. 4. 7-hour (!) on-site interview. This consists of random technical and behavioral questions, a pair-programming session (adding features to your take-home project), a personality test, and a logic test. Overall I thought the interview process was pretty good, but it's such an enormous waste of time if you don't get the job. I think I spent 15+ hours between all the interviewing and the take-home project. It's frustrating to receive a very vague reason like "not experienced enough". My experience and coding abilities should have been pretty apparent from my work history and the project that they reviewed before they called me in.
