If you are a very high experience candidate you have three job avenues:

1) A few recruiters (not many) would surely come for a high-experience roles
2) If a recruiter comes for a 5-6 years experience role but you know that their business is such that they would also need high experience candidate you can always negotiate better roles during interviews, citing your better experience
3) Off-campus: When you have a good B-school brand with you and being in business for a decade or so you would have a lot of industry connections already, I am sure it would not be tough for you to get interview airtime with the HR and senior management of companies you would want to get into. Your MBA is signal enough for your capabilities and later you can shine in the interview and get the coveted job.

Myth-Breaker

It may seem rude and my apologies if it does, but please do not enter the recruitment scene thinking grey hair get VP positions by default. You will have to prove your worth at every stage of recruitment process to get a senior position regardless of number of years in your work experience.

For the original poster, YES, it will be tough. Precisely this is the single most reason why many schools flatly refuse to admit senior guys. by the way, I am one.

Then I agree with Ivy, being in a disatvantage position, you need to act differently, you need to work extra hard from day one. And ofcourse, select a school where they have a cooperating career service, who goes the extra mile.

To me MBA is an experience and nothing comes closer to any other forms of study except FT.
