Johnson Controls Systems Applications Engineer interview questions

Interview process was as follows: Brief interview with the internal recruiter to see if you're who you say you are. A week later, a panel interview with three other people that lasted an hour. Then two weeks later, a panel interview with the same people as before. But now they've thought of more questions to ask. They seemed very unprepared this round and inexperienced in asking questions. I was asked multiple times the same question in this interview. Then after this, radio silence for two weeks after emailing and calling the recruiter multiple times for updates. Finally an email back saying that the team would have a decision by the end of the week. I never heard anything from the team after that, and quit asking them. It seemed extremely unprofessional to give zero updates. If I didn't get the job, that's fine, but at least tell me one way or the other.
