Tesla Software Engineer(Internship) interview questions

They initially rejected me, but later recruiter reached out to me since I had some projects using Golang. Interview got rescheduled twice, my initial interviewer was changed. During interview I was asked a lot of questions about network, like "what happens after you write a link in search bar in browser and click 'enter'?". After this I was given leetcode medium problem, didn't solve in optimal way :(

total 3 rounds 1hr each 0. HR reach out 1. engineer 2. engineer 3. hiring manager HR moves on very quick, about 1,2 days to get result for each round
