They must have bedn desperate to find somebody to replace the former Senior SEM Manager who has recently left Groupon. I was headhunted directly by them. HR was not able to schedule interviews - quite concerning - so the hiring manager arranged a series of Skype calls over 2 days with a lot of different people in various location. After the standard CV related questions and very few competency questions, the "best" part of those interviews was logical questions e.g. if you have 9 balls and a scales how many attempts would it take to find the heaviest ball? They went on and on with this type of questions. When I openly asked them what's the use of these questions and what type of insights on the candidate they can give, they told me they look for people with a highly logical mindset. At that point I told them that then clearly we were not a match.
