Qualcomm just closed the Seattle and Bellevue offices over the last year, and Intel is doing the same.

i have half a dozen friends who are graduating next month and going to Microsoft in Redmond. Many others going to Amazon. So not sure where you came up with this.

It's hard to disentangle if those are due to CA lay-offs or if there are less CA lay-offs because of a migration due to COLA increases (my pet theory).

source? Most entry level devs come by wave after graduation from College (+ post-graduation vacation). The number of those new college hires does not seem to have slow down, but only HR departments at those companies would know the exact trend.

Typically it would be migrating up to WA (geographically north).

Are you saying the layoff trend is migrating north? Or actual people who were laid-off are migrating north? Or something else? It wouldn't make sense for laid off workers to migrate north if there's less hiring there, but then, you're talking entry-level. I'm just not sure what's being asked here.

Facebook is aggressively hiring in WA, even offering employees in Menlo Park to relocate there while retaining their Bay Area salary.

Amazon is still hiring college grads like crazy.

Microsoft continues to hire in WA.
