Earlier quoted context omitted.

That works out to 8 million per person on average. I'd be interested to see if the Pareto distribution holds here as well, namely that 1% of employees (26) hold half the wealth ($10b).

(PSA: 50/1 is approximately the same distribution as 80/20)

It is the same distribution, just makes the point more clearly.

Its mostly done as a way to filter job applications into a smaller set. When Google was the 'hottest' job prospect (many years ago) they needed a way to reduce the set of applicants down to a number where hiring managers could handle the load. Setting criteria such as having an Ivy League degree or a CS degrees with GPA over 3.8 was a logical way to achieve this goal. That being said, if you went to a community colle…

> they needed a way to reduce the set of applicants down to a number where hiring managers could handle the load The question is what other attributes you "accidentally" filter by if you filter by school prestige. Even if you do bias your pool to individually better candidates on average, you may bias it in a lot of other ways. If the purpose of the filtering is to reduce the pool to a size where humans with common s…

They're smart enough to know how create filters that don't miss people with competitors experience on their CVs. In fact, they actively seek those people out on LinkedIn and anywhere else they can find them.

HFT jobs are high value / high comp jobs, so Jane Street and their cohorts put a lot of effort into recruiting. This includes their resume intake system, internships with desirable colleges and professional outreach.

Jane Street made 4.4bn net income in Q1 2024 w/ 2600 employees. Tether made 4.5bn net income in Q1 2024 w/ probably <50 employees.

Well, Tether only needs to hold treasuries and collect quarterly interest payments. They don't need much staff, at least if they haven't looted the treasuries SBF style.

"Jane Street has 40 “equity unit holders on a full-time basis and in good standing”, with an average tenure of 16 years" - I suspect a large portion of it would come from those 40 but that is purely a guess.

Why do they say 179,000 million instead of 179 billion? Is that common in their industry?

Why do we say 17,000 kilometers instead of 17 megameters?

I want us to start using megameters. And gigameters.

And instead of (metric) tons, I want megagrams. No kilotons; gigagrams.

If I remember correctly they are also by far the biggest poster child for OCaml, right? Blub Paradox at play here?

They're more than a poster child, they made a lot of contributions to the ecosystem. OCaml would be different without them.

I'm very much not a serious OCaml:er but when I've dabbled some in it I got the impression that their "standard library" is kind of the de facto standard library.

> Double the profit per employee than Google > Average TC of 900K > Several unranked billionaires it makes even OpenAI / Meta ML SWEs look underpaid

This is the average, it'd be interesting to know what's the median for a SWE is. Also, some high-level SWE do make 900K at Google and others. Maybe for a similar set of skills, JS doesn't pay (much) more than Meta or Google?

> This is the average, it'd be interesting to know what's the median for a SWE is.

900k is average including janitors and HR.

Median for SWE most definitely over $1 million. Turnover of 6%? No way people stick around “only” making 500-600k new grad comp. Check levels.fyi

> Also, some high-level SWE do make 900K at Google and others

And some high-level SWEs at JS make 9 figures, not 900k.

I thought the Pareto distribution was most famously associated with 80-20? Of course you can change α to get whatever ratio you want but this is the first time I heard of the 50-1 ratio being used.
