ABB Intenship interview questions

I applied online and got in contact with a recruiter. The interview went through my resume and background. The HM asked several behavioral questions. At the end of the interview, the HM said the recruiter will follow up with me and if they don't I can follow up with the HM. However, the worst part of the process of the interview was the recruiter and HMs ghosted me. This situation doesn't happen once. If you got hired, the recruiter would treat you very nicely. If you are rejected, the recruiter and the HM would ghost you.

The interview was very decent. I got an invitation email from the hiring manager directly. There're two rounds totally. The first one was a 15-min video interview. The hiring manager just asked several general questions regarding my expected graduation date, available timeframe and immigration status. The second one was a project presentation interview. There're two senior engineers interviewing me. You just needed to choose one of the projects you've done and presented the details. The whole process took about one month. I don't get any feedback after the second round. There was NO recruiter during the whole hiring process at all which is very unprofessional. I assume that they fulfilled the position already.
