Mosaic Transit Group interview questions

Received a phone call from HR which was a sort of informal HR interview. Afterwards, received an email for an interview with the hiring manager which was rescheduled 2-3 times. The interview lasted for only 20 mins as the hiring manager seemed least interested and did not even bother to take notes and asked very vague questions. It seemed that he is just fulfilling the formality by taking an interview and the candidate has already been selected.
