first head hunter contacts you, and if you agreed then there will be a phone interview and then if passed, will be asked to be on site interview - the last stage.

It was 2 rounds of technical interview followed by a fitment interview. Technical interviews went well and the questions were basically based on the projects which I was a part of in my previous organisation. The technical manager was professional and the interview went well in an interactive session. A fitment interview with the senior manager was more like a pressure testing interview, which was totally unexpected.
