Cable Care interview questions

The interview was conducted virtually. There were 5 interviewers sharing a cam in a room. (which is pretty insane for a small company) Anyway it went thru pretty normal at the beginning. But after a few minutes while I was answering the question, one of the interviewer (an auntie, name 'Sharol') kept mumbling to her peers, and both laugh. Which this happens several times during the entire session. This is very disrespecting the candidate and pretty unprofessional conduct as a 'HR person'.
