I should've checked the glassdoor reviews before wasting any time with them.
The interviewer who conducted the live demo was multitasking during the interview.
The CEO was as rude, unprofessional, and disrespectful as what is already extensively described in other reviews. He started the interview with a personal question. When I said things that he had never heard of before, he laughed in my face. It's like his knowledge is a small ball, and anything beyond it is ridiculous. Five minutes in, I knew I would never work for a person like this.
