I know something about Mercer MC recruiting, and I don't believe the 15 months would have caused your application to be rejected. Better to have a good look at your CV as you suggest - and I can have a look at it if you wish. Post an e-mail address of some sort in that case.To be perfectly frank, most firms have recruitment routines that are less impressive than you would think from the outside, and there is a chance that no-one would notice a resubmitted CV. If they did, however, they would probably be a little annoyed - but then since the processes are so ad-hoc anyway, it's not obvious that there's any blacklist to put your name on.
