I don't think I have especially cool resume or anything, nor do I have extremely many years in the industry as well, but I'd never consider applying for 100 different companies. I don't even know deeply about 100 companies I think, which is something I learn about a company before even considering applying to it.
I think I've applied to about 5 different full-time positions over the years and I have been in about 10 full-time positions in the same time, 5 of those applied to and the others was companies "applying" to me instead. Then bunch of consulting and freelancing gigs in-between.
