I was selected as part of a campus recruitment. Had a quick phone interview call and then followed up with a more technical in-person interview on campus. this was followed by a final round at the headquarters where I was interviewed by 3 separate people. the nature was mostly technology focused with a bit of generic questions. Was given an offer letter after they conducted another 3 rounds of interview - so the wait for me was a bit more. but the HR folks contacted me to state that I was a shortlisted candidate and wanted to let me know after additional rounds. Others in my interview round were told no right away. So, a bit more communication that I had expected.

I was recruited by one of the TI fellows and asked to come down to Dallas. The interview was thorough but fair. Gave a presentation to members, senior members of staff and fellows. Was asked questions about the presentation and then had individual sessions with several of the people present at the talk. The staff overall wanted to engage in a lively discussion and see what I knew, but was not disrespectful about it.
