Google · L5 Machine Learning EngineerOfferGoogle L5 machine learning engineer interview: phone screen skipped, four technical rounds, and an offer
A candidate applying for an L5 machine learning engineer role at Google had the phone screen skipped due to a referral and prior tenure at the company, then went through four technical and design rounds plus a behavioral round before receiving an L5 offer. The loop was one leg of a broader search that produced offers from several companies in the same cycle.

A redirected recruiter call turned into an Amazon Applied Scientist loop with the Alexa Speech team: a phone screen, a split five-round virtual onsite across two teams, a bar raiser, and an added ML-breadth round, ending in an offer with a downlevel from L5 to L4.
