The interview process had five phases. The first two were online tests; the first online test was logic puzzles and basic debugging of a program that has trivial bugs (syntax error, off-by-one errors, etc). The second online test had a more involved coding challenge - think two leetcode medium problems and a workflow simulation. After they process the results of those two coding challenges you are either given an additional phone screen, or move to the final round. The final round is three interviews each with a behavioral question or two and a coding test ranging from hard to medium problems. In my interviews the interviewer and myself struggled to define the problem as they were poorly explained, and in the final interview the interviewer himself was calling prior work experience as "not real experience" due to it being government work. Additionally if you have technical issues as I had in the first interview they will not give you additional time and in many cases the interviewer will be visibly/verbally annoyed that you had issues with Amazon Chime.

It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.
