Veeva Systems Software Developer interview questions

The worst interview I've ever had. Got a screen call from HR which was standard. However, once I met the interviewing manager, that's when things went downhill. The interviewing manager was 10 minutes late and when he finally joined the call he did not even apologize nor address his lateness. Then he introduced himself but did not give me any chance to introduce myself nor ask him questions. After that, he went straight to a leet code question that has nothing to do with their everyday work. Throughout the interview he was very disinterested and when I finished my work and told him I finished my work it was clear he was not paying attention as he did not respond for nearly 5 minutes and instead I could see through the reflection his glasses that he was on messenger. After the interview I quickly emailed the recruiter that I am not interested in continuing. This interview was one of the most unprofessional and disrespectful process I've encountered.
