I have recently completed the interview process with a new employer. Tomorrow, they will call me to discuss the offer.
However, I think I would be at a disadvantage in a real-time conversation. I have done some research, but this position is the first of its kind on this team, so there's no direct salary information available. The company is very successful, so I believe they can offer well above generic market rate. So this brings me to my questions:
a) How do I tactfully move the conversation from phone to email? Do I just say "let me think about it" or should I give some kind of tacit acceptance/assurance?
b) When should I try and do this? Should I attempt to negotiate on the phone and put my cards on the table first, or just go as far as necessary to get some kind of number, and counter-offer only in email?
c) Should I do this at all or is a live negotiation actually beneficial somehow?
