You're hiring because you've got a bit more work than you have people for. You're probably under a bit of stress, timelines are a bit tight.

Do you want someone who has strong evidence of job-hopping, and believe they will commit more time than average to your environment, on the basis that the job hopping is due to high performance?

Or do you want someone who's going to stick around a bit longer, on the basis that much of the value of someone in a job is actually domain knowledge specific to the business and the code, rather than transferrable skills?

When I see a lot of job hopping on a CV, I tend not to take a chance. Those folks haven't shown evidence of investing in non-transferrable knowledge and processes. They might have high performance transferrable skills, but chances are they'll want to change how things are done, then not stick around to see them all the way through.
