Deel interview questions

Horrible interview process. I made it through 3 rounds of interviews, including 1 mock sales demo, and was moved to the 4th and final round. Before the 4th round the recruiter messages me saying "the VP has some concerns in my resume" and the 4th interview was cancelled. (This is what screening calls are for, absolutely insane thing to hear after being moved to the 4th and final round??????) The recruiter and myself hopped on a call to talk through the concerns and we rescheduled the final interview for the following Monday at 2:30pm. The following Monday rolls around and the interview was cancelled again at 2:31pm. I'm so upset I wasted this much time preparing and interviewing. The entire process was extremely unorganized and unprofessional.

30 minutes of duration, the interviewer was very kind and I felt very good. I only had one interview and it was just a screening process with no hard questions.
