Tripadvisor Software Engineer(Internship) interview questions

(November 2019) First I had a brief interview with a recruiter on campus, then I was invited to a virtual interview with a software developer and she asked a simple programming question. Then I was invited to a code challenge that I had to design, implement, and test a small system. Finally, I got three consecutive interviews on-site, where two of them were programming and one was HR. I finally got the offer; however, duo to COVID-19, TripAdvisor revoked all internship offers.
