Being a recruiter is not easy. It can be frustrating but also really rewarding all at the same time. We are human beings and can make mistakes but please DO NOT tell a candidate to **** off. If you need to vent or need a break from work then take a vacation but you should never blow up on a candidate and then accidentally email 4,000 people.

I just hope everyone knows that "..we are all not like Gary Chaplin".
