Looloo Technology interview questions

I went through all three rounds of the process, and it was the worst interview experience I’ve ever had. First round: I had to take an IQ test (why?) and complete LeetCode questions online. Second round: More LeetCode questions online (again). Final round: HR told me it would be a behavioral interview with the co-founder, but the co-founder asked LeetCode questions again (this company really obsess with leetcode). The interviewer was very rude. He spoke in a dehumanizing and insulting way, looked down on my abilities, showed no respect, and created a toxic atmosphere. I quit to end the interview and would not recommend anyone apply to this company.
