Disclaimer - I know nothing about anything.Moving on, I wonder whether it's really worth the year out and what I assume is >£20k debt. Perhaps it is, particularly for MBB. But I would be surprised if you couldn't crack big 4 given your background without a masters, albeit you may need to take a step back to do it. My guess is that if you can't break in to big 4 now, the masters won't help. MBB is a different beast though.P.S. read the disclaimer.
