What you're facing is the common situation of 'benefit now versus percieved benefit later. Having just landed a role back in industry, on the back of 5 years consultancy, I would strongly advise on taking the industry option, if you can answer yes to the two following questions.1 - Have you shown clear ability to deliver and progress in your previous jobs?2 - Are your previous employers solid blue chips?If the answer to both of these is yes, I feel you given your background that you would gain a limited amount from the MBB environment, and potentially risk a lot in taking this path.From my recent experience in the recruitment process, emplyers are interested in where you have come from, but more interested in you and your ability to delvier and progress.
