Engine Senior Frontend Engineer interview questions

I was contacted by a recruiter on LinkedIn, and the entire hiring process took less than two weeks. Everything was conducted in a highly professional and respectful manner. The process consisted of a conversation with the engineering manager, followed by a live coding session and a system design challenge. Although I did not pass the challenges, the recruiter sent an email the very next day with detailed, constructive feedback explaining why. I truly appreciated this, as it gave me a clear understanding of the areas I need to improve. It's rare to receive such thoughtful feedback after an interview.
