As expected from a Google interview, it consists of a phone interview and a technical interview. In my opinion, with the skill level Google is looking for, the interview is fair and accurately tests the ability of a candidate. I imagine the interview for full-time positions is harder, but as an intern, I felt that it was the right amount of difficulty and complexity.

there is no online assessment, very simple phone call, then two technicals. technicals are not difficult by any means. then you get put into team matching, after a couple months

Resume screening and then two 2 rounds of technical interviews, on an elimination basis. Interview done on google docs with no IDE, dsa leetcode style question. May be asked follow up questions on how to optimise your solution or on how you would code up a solution to a similar problem.
