Optum Intern interview questions

Applied online & after a few days got the link for written test on Hacker Rank that's how it started. Round 1 - MCQ(APTITUDE + Technical) + 1 or 2 coding problem(s), Round 2- Technical Interview. The focus was on understanding core DS concepts & OOPS. If you understand the basics well & have done some hands-on programming this round won't be an ordeal. 2 weeks after this I got a call from HR & was offered an internship.
