I was referred by a current employee on the Monday. Had an email requesting a telephone screening on the Tuesday. Completed the 20min screening on the Wednesday. Still another 4 stages of the recruitment process to go, hence why no offer yet.

1) 1 round of a telephonic interview that runs for about an hour. Usual questions about the background and a case study to understand the candidate's thought process and problem solving capability. 2) Technical Round at ThoughtWorks' office. Questions very similar to the telephonic round and a case study to test problem solving and innovative thinking capabilities. A few additional questions regarding the challenges in day to day work If you get through the first round, there will be others.
