Cox Automotive Software Engineer interview questions

Got a take home programming exercise and a Google form. Exercise takes about 1 hour. Submitted both and got selected for phone interview. Phone interview is about an hour with some basic tech questions and 3 small programming questions. Immediately got selected for the next round which is a on-site interview. This is the most disorganized and unprofessional interview I have attended so far. I was sent a format for the interview and nothing was followed. Supposed to be 3 hours long and had 3 interviews starting with a code review of the take home assignment. I was given a basic tour of the office and the manager started asking me basic questions about AWS migration and related questions and after a few another Senior Dev and Manager came in and asked couple more questions and left. No code review or testing my technical skills. And I was sent a basic not selected email without any feedback. Looked to me like they already hired someone for the position and just interviewed me just because they already scheduled an interview.
