After staying at one job for way too long 10 years ago, I’ve hopped jobs 4 times, pursuing that strategy (and learning about modern architecture) and have seen jumps of $7K, $10K, $25K, and $20K. Unless the market sours, I should be able to put together a resume and skillset to get another $25K bump as a consultant within the next 3 years.
This isn’t in Silicon Valley, NY, or DC.
I can’t see an MBA helping.
