Sent application, did one way interview purely behavioral, then asked for more information about my goals (like a cover letter with more structure), then had a 1 hour interview (technical/leetcode and behavioral) then a 3 hour final interview where there was 3 interviewers and each interview was 45 minutes followed by a 15 minute break.

first round simple coding question with followups, second round 3 back to back loops of Leetcode mediums (all common interview questions in the Leetcode 150). Also one generic behavioral question per loop, something like "tell me a time you challenged yourself" or "how do you learn new skills".
