Synchrony Senior Data Engineer interview questions

Unprofessional, no introductions no interactions with the candidate. For the entire one hour slot was just asked to share a notebook and write codes for one after another problems as a live coding exercise where 3 interviewers were looking over the shoulder. Questions around the problem were not being clarified just asked to write whatever you think, again no interactions just 3 interviewers looking coldly over your shoulder. Have given many interviews that had live coding exercise but never faced such an unprofessional panel.
