This is actually very common, especially in "bulge" tier companies. My best friend interned at GS and has accepted a job there; apparently, all newly-hired analyst/traders bust their ass for the first 2 or 3 ish years before getting "hired away" by a better paying, less demanding company (typically in private equity, VC, asset management, etc). Same happens in the accounting industry.

Yeah, it's a bit of a trope like "worked at NASA" (atm over 17.000 people work at NASA). "Worked at" means nothing; show us some achievements.

I cleaned those NASA-toilets super clean, good sir, so I find no reason why you shouldn't trust me on my knowledge about aerodynamics!

The new Star Wars movies have cemented that this is acceptable.

Knowledge of fluid dynamics, on the other hand... :-)

To be fair, a lot of those companies have very rigorous hiring standards. Also many are pretty quick to let people go.

So "hired by GS then left on my terms" is actually a pretty good credential.
