Thoughtworks Project Manager interview questions

Interviewed by HR on agile experience and asked to attend a weekend workshop. Called for workshop which was from 9:30 - 5:00 pm on a Saturday. 20 people ( mostly referrals and service backgrounds ) were called and drilled about TW's philosophy, agile driven methodology & open source contributions to society. A case study was given and 3 teams of 4 each were given time to present it. How this exercise made them decide who to call for the next rounds is a pandora box? Consultants having DEV/QA background were introducing themselves as having proudly moved to office management and interview hiring. Career growth path seems to be very confusing and divergent for the role being hired for.
