You'll get a job- but agree with the above,think very hard as the bottom end of the consulting ladder can mean a lot of time away from home until you establish your network, build a client list etc and can get on the jobs you want.MBA isn't neccessary unless you want to go to one of the big strategy houses- and they may not like your charity background.If you're sure this is what you want to do, I'd recommend you start looking at some of the mid-size to niche firms with strong public sector teams... find out a recruiter's name, then call then up and have a chat. Good luck!
