Internal recruiter, more than 20 emails back and forth to set up an initial phone screen, more than 100 total by the end of the face to face on site group interview.
Email at 11pm is designed to see how much of your personal life you will give to them... Maybe the Inovalon recruiter I was assigned was a bit eccentric, or maybe this is a gristmill that fresh grads with little or no experience can learn what micro management and soul sucking corporate is all about.
