What if we gave them the benefit of the doubt, and they were posting "no more than 12 years" because they want someone who's seen what happens but not someone who is steeped in it? Someone who is familiar with the problems but hasn't dealt with it so long that they are still naively excited about trying to change it?

For example, if x guy has been doing TPS reports for 12 years,maybe they are figuring that he has already just adjusted to a gotta-do-my-TPS-reports mindset?

just giving some benefit of the doubt
