Microsoft Software Engineer Intern interview questions

Got an OA in which I had to solve 3 Leet Code problems in 90 minutes. Wasn't horrible but I wasn't great at all of these data structures and algorithms problems so I didn't pass.

Applied on their portal, and within about a week got an email asking me to schedule an interview and take an online coding assessment. The coding assessment isn't too bad, 2 easy questions and 1 medium. The interview goes a bit more in-depth about my history with programming and previous projects worked on, asks you to explain a core programming / OS concept, and finally asks you to solve a brain-teaser/riddle style problem unrelated to coding.
