Lemonade Insurance Backend Developer interview questions

First interview was online and technical, followed by an home assignment (given a week to implement), and the next interviews were HR and director. The whole process took around 2 weeks

The interviewer was not interested from the beginning. He would cover his mouth, blinking eyes, mouth, and spoke in a monotone so it was extremely hard to hear him. He only explained about the company and his role but didn't ask me anything about my skills and introduction. I introduce myself and explained my skills. If you are not interested to take interview then why do you schedule interview and waste candidate time.
