Applied online, no referral. Signed an NDA so no specific details provided below but rather a high-level overview. 1st round was a typical HR screen "tell me about yourself, what you're looking for etc". Asked if I'd be comfortable with RTO 5 days/week at their Newark office. 2nd round was a tech screen with a few different parts: 1) LC style coding - first question was a basic hashmap question, next question was a tricky variant of two-sum. 2) ML theory - refresh your fundamentals on loss functions, metrics, statistical tests / concepts (ex. independence) 3) Resume deep-dive. I moved on to the on-site, but I was never told what to expect for each round even though I asked 3 times over a couple of weeks. Very, very unprofessional. but sadly a common experience these days in the interview process. I withdrew from the process as I already received an offer.
