This was on of the most unprofessional interview I had ever had. It started out with them joining and just introducing their name and saying ok lets jump into this writing exercise. Said nothing about the company, role, and did not ask us (yes, it was a multiple person interview) to so much as introduce ourself. They muted themselves after a minute and said ok you have 20 minutes, I was stunned. I see this with employers when they interview students-do not value their time by introducing us to the role and interviewing one on one.
