My question is about staffing firms. If one receives an additional offer besides the one the recruiter was able to get, during the "think about it phase", is it a good idea to tell the recruiter about the other offer? What would be a good tactic to increase the initial offer from the recruiter, in this situation? Would the recruiter dig into the company name and the offer details or probably take the candidates word for it and try to meet them in the middle?
