Drw Quantitative Researcher interview experience

After the initial screening steps, I was asked multiple probability questions with a Bayesian thread: it started from a basic Bayes theorem setup and then evolved toward more advanced modeling ideas like ridge regression and lasso regression.

Then I did live coding on a platform. The task wasn’t just about writing something that compiles; I was given an array and asked to write a function to compute the lengths of increasing sub-arrays. The combination was interesting to me because it wasn’t purely textbook probability—it forced me to translate math thinking into an algorithmic
