Google L4 Cloud Software Engineer Interview: Downleveled to L3

A referred candidate interviewed for an L4 software engineer role on a Google Cloud team in Bangalore, going through a phone screen, three onsite coding rounds (the third left unfinished), and a culture conversation, only to have the hiring committee offer L3 instead of L4; the candidate obtained the compensation letter and declined the next day because the pay was below their current salary.

Google L3 software engineer interview: phone screen, four coding rounds, and the Googleyness round

A candidate with two years of experience went from recruiter outreach to offer over about four months. The onsite was four 45-minute coding rounds — three of them featuring binary trees — and one round turned into a 25-minute chain of follow-ups about approximating an optimal solution at scale.

Google L4 Software Engineer Interview: Eight Rounds, No Offer

An L4 Software Engineer candidate went through two phone screens, three onsite rounds, a culture conversation, and a team-matching call with a Google hiring manager, then watched the process stall for about a month and a half over a tightened experience requirement before an added extended round ended without an offer.
