We had a coding round first, with two questions. These were Easy LeetCode level.

Then, we proceeded to the next round with the shortlisted candidates. The first round focused on Data Structures and Algorithms (DSA).

The interviewer asked a few basic questions about myself and my projects, then presented a question. This was a mid-level question, but the interviewer kept disappearing every five minutes, instructing me to think for ten minutes. This one question took forty-five minutes to complete due to these interruptions.

Afterward, I was asked to dry run the code I had written and to state its time and space complexities. The interviewer left or got disconnected at the one-hour mark, which was the interview duration. I tried to re-establish contact as I was still on the call, but I couldn't.

Apparently, other candidates in my batch were asked two questions. Those who answered both were shortlisted for round two, where they were asked Machine Learning related questions.
