This sympathetic onlooker does not have public sector consulting experience, and can’t really help you other than to reiterate that you appear to be acting very responsibly. It either reads like a hare and tortoise story, or the nearest-interview miss that I have ever heard of. It is difficult to put aside the speed and ‘quasi’ procedure of putting you in front of such a large client so soon, before apparently agreeing the contract, which seems to be very bad practice. However this probably has little capital in terms of landing your next consulting role. EITHER: Take Recruit Gals initial advice (you might already know that she very frequently offers excellent recruitment advice?). You might consider finding an acceptable compromise (a fourth interview?? Meeting at a different client site??? Contacting and meeting with a decision maker at the firm?) OR: Wait for them to react/Let them know that you are no longer really interested. Consider other more suitable opportunities, safe in the knowledge that if you can get to stage 3 in an unfair process, then you could breeze through a fair one. Some might choose both options.What is certainly true, to my thinking, is that I would not wish to interview for the same role as you, if you choose the ‘OR’ option!
