DistroScale interview questions

The worst experience I've ever had. Initial phone call talked about your project, then being informed that the onsite was to implement the actual feature instead of algos. Super small company, there were 5 people top. Then, I was put into a room, given a touch-pad broken mac air and coded the thing. Later on, the interviewer checked my progress and I finished a small portion of it. He immediately terminated the process and decided to kick me out. It's been only 90mins, and I was promised to have 5-hr onsite. I understand they're not moving forward because of my performance, but before I left, he lectured me. He sounded like I knew nothing and was super lame, and I quote "your ability is not even matching the average level as a full-stack". This is an entry-level job btw, I felt insulted and humiliated.
