I read that a different way. I understood it as an ad from Company X which lists '5 years of Python' as the requirement. Candidate 1 has 5 years of Python at Google, and Candidate 2 has 5 years Python at InfoSys.
Does the Google experience really teach one that much better? Or is it just perception?
I mean, at the end you are just a little cogwheel in some big corporation anyway. The python tasks you need to solve there are probably just as mundane as everywhere else.
