Oh come on, this is so untrue. Silicon Valley loves credentialism and networking, probably more than anywhere else. Except the credentials are the companies you’ve worked for or whether you know some founder or VC, instead of what school you went to or which degrees you have.
I went to a smaller college that the big tech firms didn’t really recruit from. I spent the first ~5 years of my career working for a couple smaller companies without much SV presence. Somehow I lucked into landing a role at a big company that almost everyone has definitely heard of. I didn’t find my coworkers to necessarily be any smarter or harder working than the people I worked with previously. But when I decided it was time to move on, companies that never gave me the time of day before were responding to my cold applies or even reaching out to _me_ to beg me to interview.
And don’t get me started on the senior leadership and execs I’ve seen absolutely run an entire business units into the ground and lose millions of dollars and cost people their jobs, only to “part ways” with the company, then immediately turn around and raise millions of dollars from the same guys whose money they just lost.
