I've heard this mentioned a lot but how often does it happen and how much of a risk is it? Employees developing IP in personal time doesn't seem like it would be that common.
As a Google employee, Google owns everything you make even in your free time unless you go through some kind of process. Never worked there so don't know the details but have had it confirmed from other Google engineers.
Some other companies got this idea as well, but it's usually very easy to get that removed from an offer.
