"Take the highest offer and ask the lowest if they can beat it. Repeat until a recruiter gets annoyed.
Never negotiated with multiple offers. Will try the same. How do you know if the recruiter gets annoyed?
They start giving you funny looks and aren't as enthusiastic in their call. From my experience it happens either when you ask for a second or third increase."
