Well known to Ivy-League undergrads and FAANG engineers for having some of the highest paying jobs available.

Interestingly enough Jane Street has a fairly negative reputation within certain engineering schools that they love to recruit from. Hard to hire talented and passionate people if the only thing you can offer is a bit more money at the expense of everything else people look for in a job.

I interviewed there a few years ago. It wasn't bad, but I had a much more pleasant experience with FAANG (specifically Google and Facebook).

Jane Street has spent a lot of resources into making sure they're well known as one of the "top employers". Their recruiters put a lot of effort into pseudo-anonymously promoting the company on websites like reddit and blind. It's pretty forward thinking actually as younger tech savvy candidates no longer pay attention to sites like glassdoor and seek information through these discussion forums. The natural evolution of fake glassdoor reviews is astroturfing I guess.

Firm performance is excellent but IMHO the only reason to work there as an engineer is for marginally more money.

it's well known as a top tier market making firm. They're not as special as they are made out to be, though. They just have good marketing.

Often mentioned on Blind as one of the places top engineers can be paid handsomely.

i grind php daily, and am aware of them
