I was hoping that those of you with more experience within the big 6 (ACN, PwC, IBM, Atos, PA etc) could answer the following questions for me?1) Which of the above have the practice of offering sign on bonuses at the principal consultant level? If so how much?2) Once offered what is the maximum time you can 'sit' on the offer, i.e. wait for outcomes from other interviews before making a decision?3) Are there any precedents set for deferring acceptance of a role, e.g six months, 12 months?All of these questions are hypothetical at the moment but its difficult to find answers and I think knowledge of the above would put me in a much better position when it comes to bargaining/accepting an offer when the time comes.I thank you in advance for your help!!Jim
