Groupon Product Manager interview questions

Received offer but rejected because of loss of trust in leadership through the interview process. Invested 4+ weeks to receive an offer which was for a temporary contract position. It was obvious that leadership had consciously made the decision to hide this until the very end of the process. Not sure what the intention was here, but it would have been easier for everyone involved to be transparent from the initial recruitment call. I hope no candidate has to go through this again.
