What does a quant do? Machine learning, linear regression, moving averages? Lots of statistics on time series data?

On the machine learning side, in my experience it’s often simple, linear models that work best in the messy world of financial data. I’m sure there are shops out there breaking out the GPU clusters and training NNs with 6 trillion parameters but in no way will your super deep NN guarantee alpha whatsoever.

You'd be more likely to find deriv quants at a bank selling such things to people, whereas the strategy quants would be what you'd find in the funds.
But even within that fund side I'd imagine the job looks very different depending on what firm you're at and what they ask you to do. Not everything is glamourous blue-sky "what should I buy or sell" stuff. A fair bit of it is things like cleaning the data. And there's going to be a lot of tooling. Since nobody says what they are doing, everyone has their own version of a research pipeline, and that needs to be kept clean. Likewise on the execution side, there's a load of code to be looked at, and a lot of data coming out relating to trading costs and such.

#16This has always been true, for the entirety of my career. Buy side pays more than sell side for alpha-generating activities. (Sell side pays more for flow and scaling advantages.)
This article strikes me as a submarine [1] for Baruch’s program.

In short it's trying to find the signal in a huge amount of noise/data.
I'm not a quant but I support the Quants at my firm. Some of our datasets are hundreds of millions of rows with up to 450 factors/features per row.
They also run NLP on terabytes of SEC filings (like quarterly and annual reports). Not sure how they analyze the results of that.
