No that's MLE. A DS rarely gets asked leetcode algos questions, an MLE would.

You must have worked at different places from me. Nearly every DS job I had (before wisely apparently) leaving that area had leetcode style algo questions during the interviews. Again, things have apparently changed.

Depends on the company, a research level MLE would be asked to derive loss functions and perform partial differentiation on pen and paper. You have to answer questions like what Kullbeck Leiber divergence is and how it can be utilized etc.

  Would that be a lesser known cousin of the better known Kullback–Leibler separation measure for distributions?

    Full marks for snark, but points off for being incorrect. https://en.m.wikipedia.org/wiki/Kullback%E2%80%93Leibler_divergence https://en.m.wikipedia.org/wiki/Kullback%E2%80%93Leibler_div...

      From your link: a measure of how one probability distribution P is different from a second, ie. literally it's a separation measure for distributions .. just as I recalled from my first encounter with the notion ~ 1984 (ish). If you're sincere you should either add those points back or, preferably, expand upon your theory of how my snap take is incorrect. ( I'm aware it's not a metric due to triangle inequality, etc. )

        The snap take came across as an argument about which of two names for the measure is better-known. The wikipedia page implies the opposite of that argument. Perhaps that’s changed since 1984, but the proposition was about current practices.

        It's been Kullback since birth in 1907 to the best of my knowledge, never once Kullbeck. As a fully anglicized US citizen born in Brooklyn, New York I don't think there's ever been any vowel confusion over the spelling of the name: https://en.m.wikipedia.org/wiki/Solomon_Kullback https://en.m.wikipedia.org/wiki/Solomon_Kullback Admittedly I did check as it's not uncommon for mathematicians to have alternate spellings for their names. Ditto Leibler, born Chicago, Illinois in 1914, no dropped L https://en.m.wikipedia.org/wiki/Richard_Leibler https://en.m.wikipedia.org/wiki/Richard_Leibler

I literally was asked two leetcode questions verbatim when interviewing for a data science position at TikTok a few months ago. Dynamic programming (I won't mention which question) and then one regarding binary trees.

    Alternatively, protect themselves since giving away an individualized question could identify them.

    The question does not matter at all. All of the information in the knowledge of Leetcode + category. (Does it really matter WHICH question?? They are different but all the same. That is the point.)
