HR contacted and set up an interview for the next day. I went in and met up with two engineers and talked about the role about 2-3 hours followed by lunch. Another interview after that day was set up with the higher ups. Since that day, I have not been able to get a hold of HR and I got ghosted. They did not reply to my Email nor did they answer my text message to the HR lady, this is just rude.

1) the first is HR interview,the background of you, why did you apply it, 2) the second is a technique interview, they will ask you the questions on your resume, your experience, your project, your skills, 3) the final interview
