Tata 1mg Backend Developer Intern interview questions

I applied for the internship through a referral from my friend. In the first round, I was asked two DSA questions. The first was a basic string problem, and the second was a slightly tricky one named "Zigzag Conversion" from LeetCode. After that, I was asked a few conceptual questions on Database Management Systems (DBMS), Operating Systems, and Object-Oriented Programming (OOP). I was then selected for the second round, which started with a discussion about my projects. Following this, I was given an implementation-based problem, "LRU Cache" from LeetCode. I solved it in approximately 40 minutes during the one-hour interview. A few days later, I received a call from the HR team informing me that I had been selected for the internship.
