Met an engineer with an MBA working in my company as product manager. He did his MBA from HEC Montreal. He was saying that do't expect a salary increase of 90 % after MBA... And a reasonable increase will be 30-40 %. Well, if I have to spend 370 K dollars (As is the cost of Harvard MBA), how many years will it take me to earn this money back. About 15 years...

I guess, it is only my company who doesn't give any significant incentive to engineers and MBAs. Grass is greener in other companies....
