I am currently in the early stages of interviewing with MBB, and the recruiter said that if I move on I will need to inform my current employer (large energy company). I assume this is because we are regular clients, but I am little concerned about "Tipping my hand" to my emplyer and potential repercussions if I dont get this job. Anyone else had a similar experience? Can I refuse this request from the MBB firm?
EDIT: thanks all for your tips and suggestions! Further information is that I am in the southern USA, applying to an office in this region. I will try to work with the recruiter to evaluate at what stage is most appropriate to disclose my interview. I like the idea of the conditional offer and will ask about it. We are in a volatile industry right now and don't want to give any reason to be excused!
