I applied through a recruiter. The process took 5 days. I interviewed at IHS Markit (London, England) in Oct 2010
Interview
Technical test followed by a round with the team lead, then with the HR, then the global support lead in the US and finally the overall area boss.
Only the first round had a bit of technical questions and puzzles.
