This question already has an answer here:
I have received two offers, both verbal awaiting specific details about pay etc. I have a clear preference for one of them but they have been quite slow in the process, both jobs are through headhunters. How do I inform the preferred headhunter of my other offer so they can tell the company speed up the process, I don't want to accept the other offer and then back out later, but I'm worried I may have to end up doing that. Any other suggestions how to handle the situation? The other headhunter is saying that if I accept their verbal offer, I need to withdraw all my other offers/interviews, but what happens if it falls through. How can I delay this or should I, awaiting for my preferred offer?
