Oh, similar story! I used to live in Montgomery County, and I interviewed with Palantir precisely because it was a top-tier tech company that I wouldn't have to move for (albeit the commute wouldn't have been amazing). I didn't take interview preparation seriously though and flubbed the interview, so nothing came of it. I did end up relocating to NYC to work a different top-tier tech company that has an engineering office here but not really one in DC.

I've basically taken every good job offer I've had in my life, and I haven't regretted one jump.
