I applied online and received an email a couple of days later to schedule an interview call.

There were two 45-minute interview calls back-to-back.

The first interviewer was friendly and helpful. As others have mentioned, it felt more like a discussion.

The second interviewer, however, was rather curt and rude. He had a strong accent and initially explained the problem poorly. It took me a good 7-8 minutes to understand the problem statement, which could have been easily explained in two sentences, or even better, typed out. From then on, he was completely silent and gave one-word answers to my queries.

It was quite a contrasting experience between the two interviewers.

String manipulation questions, I'd say equivalent to LeetCode 'medium' level difficulty.
