Let's pick a huge employer in Silicon Valley, Facebook, and search for jobs on Indeed.
Not a single Software Engineer position.
And I really don't think hot San Francisco startups are using Indeed to look for talent, which is why SF falls so low on their rankings
Tier one employers don't normally advertise on indeed
Which is also why Indeed's previous article "Where are the Highest Paying Tech Jobs in the US" is complete garbage. Shows SV average at $111k. SV and SF have disproportionately high portion of Tier 1 companies and positions, many of which will never show up on Indeed.
How can you talk about SV without Facebook? Facebook has 20k employees, about half of them in SV.
