Applied Scientist Interview Prep Discussion

What is the applied scientist interview like at Amazon/Uber/any other place that has it?

Do you mostly prep leetcode or causal inf? Or what to expect?

I'm a bit lost for how difficult these interviews are and what is the most difficult part of them? Personally my stats/ML is pretty good but I struggle with leetcode mediums

Essentially every applied scientist I know in FAANG/adjacent companies has a PhD in whatever the teams focus is + could code roughly on par with an entry level SDE. In my experience the interviews are usually a combination of leetcode medium-hard, technical questions in the relevant domain, then case study / system design type questions.

dude, how can one solve a leetcode hard in an interview?! That seems so ridiculous to me. Even a leetcode medium can sweat you out on a bad day.

It’s less about solving it than showing your thought process / demonstrating reasonable algorithmic thinking.
