I run an ML team in fintech, and am currently hiring. If a resumè came across my desk with this "skill set" I'd laugh my ass off. My job and my team's jobs are extremely stressful because we ship models that impact people's finances. If we mess up our customers lose their goddamn minds.

Most of the ML candidates I see now are all "working with LLMs". Most of the ML engineers I know in the industry who are actually shipping valuable models, are not.

Cool, you made a chatbot that annoys your users.

Let me know when you've shipped a fraud model that requires four 9's, 100ms latency, with 50,000 calls an hour, 80% recall and 50% precision.

What does 50% precision mean in this case? I know 50% accuracy might mean P(fraud_predicted | fraud) = 50%, but I don't understand what you mean by precision?

[chychiu]

Precision = True Positive / (True Positive + False Positive) = 1 - False Positive Rate

On that note, I'm surprised the precision / recall for fin models are 80% / 50%

I'd hope you're shipping _anti_-fraud models. Fraud models are abundant in fintech. On a side note, anyone who _really_ knows LLMs will be able to do your primitive fintech models with their eyes closed. You don't need a ton of skill to build a logistic regression model that runs at 14 qps. :-)
