Tesla Electrical Controls Engineer interview questions

Well I had a good and bad experience, first step was with the HR 30 min call, after i did a 30 min face call with the manager and then i did 1 hour test, after the test 10 min call with HR asking some stuff about the test, after i had another 1hr meeting with the manager to discuss about the test and after that i had no answer from their side, i sent an email to HR to ask for a feedback and seems they are ghosting me, I think is kind rude since i put a lot of my time for this process, studying for the test, changing my schedules to make time for the interview etc..
