Dell Technologies interview questions

I was first contacted via email to setup a phone interview, which was scheduled for the following day. Phone interview lasted 30 minutes, with general questions about skills and background. Face to face/panel interview was then scheduled via email to take place 12 days after the phone interview. Job description/Phone interview did not seem to match what was being discussed in face to face and I left feeling like I wasted my time. In addition, some of my questions were met with sarcasm, which I felt unprofessional. Hiring manager seemed uninterested, which could have been a tactic, or was true to the situation. I was not offered the position and based on my experience, I am glad I was not.
