I almost did. My professor would become Google's director of research and when she did she encouraged me to send a CV as I was about to finish my degree in C.S. I sent it but didn't get hired. Maybe I was just not Google material (i.e.: not good enough) but the official answer I got was that they were focussing on hiring U.S. residents at that point which I wasn't.
I remember reading stories from the era following this (maybe the late 2000's) where getting hired by Google was incredibly difficult. As in "You're already a superstar, waste 6 months of your time going through a complicated and disorganized process, and still get rejected" difficult. Made me wonder how they actually managed to hire anyone, let alone thousands of employees.
Google were not "evil" for a long time after this. They really were a force for good in the world for a long time. I have never admired a large company so much as I did the Google of the early 2000s. Youthful, gifted, moral, crazily ambitious, constantly doing things I thought impossible…
The "evil" only really crept in once they started to take over all of the world's advertising.
If you think that's when "evil" crept in, you really should think again how "evil" works - or, how would you implement and scale such a business model. Hint: long before they even started taking over the world of ads. The goals were defined at the beginning.
This is a common pattern that companies follow; make a good product now, make money later. Many products become crappy and companies go sour when they turn this corner.
