Frankly, looking at most people I know who want to
work for big companies but don't, these people aren't
cut out for big companies.
Having spent about three years working for a large software company that is actually horrible at software, I can firmly say the following: size does not matter. A lot of the old-school large companies moved sideways into software and don't really have the competence to deliver good projects.Also, since when do the large companies value creativity?
