The interview started with a design round. They asked about designing a TinyURL service, which was a nice one-hour discussion, mostly focused on the database part.

The second round was a coding round on the HackerRank platform with Hari, the CTO. He asked two questions, which were easy ones related to strings. Each question had 13 test cases. I was able to code for both, and all 26 test cases passed (100% score).

However, after a couple of days, HR emailed to say I was not selected for the next round.

I asked for feedback, but even HR was not sure.

After this, 3-4 more technical rounds were expected.
