it was 1 easy leetcode question

They asked multiple questions but in 3rd round there were 2 leads and both were not even interested to listen any single answer completely and they were googling everything to ask or even to verify. They asked me to write code on white board, so I wrote but they didn't even look at that. It seemed like they made up their mind about not hiring me from the beginning. No introduction, no listening, and no interest at all. Two of the worst interviewers I faced. They seemed to be lead but they know nothing. The funny part was a moment where I told them that "Springboot by default provide Apache Tomcat as a server", so the interview asked that "is it Apache Tomcat or Embedded Tomcat" and I was like "Whatt??". Now you can guess that which kind of genius they have.
