Vanguard Application Engineer interview questions

sent me an email with an online technical, had a few mc questions and a few leetcode coding questions. then i had to wait a few days and they called me to schedule the final interview. during the final interview, there were 2 rounds each were an hour long. one part was the technical and the second part was behavioral. during the technical, there's 2 problems. one was like a system design and the other was another leetcode problem.

HR reached out then set up for online OA which consist of MCQ and three leetcode questions if you pass then you get a technical interview followed by a behavior interview
