UBS Associate Director interview questions

Interviewer wasn't involved , he even didn't know for which role he was hiring for just asking program after program, copy pasting program questions from leetcode or something and asked to execute. JDk8 Check for Balanced Brackets in an expression (well-formedness) At the end had few questions about the role and all, he didnt knew anything. he said he is there for 1st round of interview nothing else, he doesnt know anything.
