MathWorks Engineer In EDG interview questions

Received a HackerRank OA and a HireVue with basic LC-styled and BQs respectively. Got an email to schedule a meet with Manager. In that call, talked about my background and deep-dived into one of my experiences. Also discussed the role and interest areas. Got a mail from a recruiter about 10 days later for scheduling the final interviews. Recruiter asked a bit about visa-status, graduation dates and stuff like that. It was virtual on-site interviews. 4 hours of interviews back to back with 15 minute breaks. First was a 2 hour technical round with an engineer in the EDG. Asked deep technical questions about one of my resume experiences. Then was asked a low-level system design question about designing a movie-ticket booking system. Had to code the entire thing and use OOP concepts. Then moved to a coding question. It was a 2 pointer logic question. Then in the last 15 minutes he asked me another question which was a DP question but asked me to solve using any other simpler approach. Just giving the approach was enough for the last question. 1 hour Behavioural rounds with the manager and an HR each. Got asked all the basic BQs you'd expect. This part was very chill, they didn't expect any particular sort of answers, just seemed like an informal chat. About 3 days later, I got a call for background check. 3 days after that I received a verbal offer from the manager which was materialised into an official offer letter next day.
