ISAT Total Support Project Engineer interview questions

Talked with recruiter, set up an interview, then arrived at my interview and was questioned by a panel of 3 people. The frustrating part is that they ghosted after the interview, the recruiter didn't respond to any of my calls, and when I tried to reach out to the head guy who interview me, he didn't give a response either.

The first interview was set up over e-mail and was with a Technical Support Manager. The interview was first about the company and second about my resume and skills. The second interview was a week later with another Technical Support Manager and a Regional Manager going over my resume, skills, and some situational questions.
