Overall, when it comes to work experience quality matters much more than quantity. I've been told this multiple times by program directors, students, faculty etc.
That is true, but the fallacy is thinking that someone with the quantity lacks quality.
Highly motivated people don't work hard for 2 years and cruise for the next 3. They show continued excellence over 4, 5, 6 years. All things equal, a highly motivated individual with 5 years of experience will have more to contribute than another highly motivated person with 2 years.
But I think the real hurdle will be that someone with 2 years is going to have a hard time finding a job post MBA. Most general/operations management position require 5 years or more pre MBA experience.
