I received an email from an HR after participating in an online competition. The first round was an online coding interview with an engineer from their team. I did not go beyond the telephonic round.

OA with 2 medium problems & a code review, 1-hour 1st round technical interview followed by 3 consecutive 1-hour technical interviews. The interviewers were all super nice. They were willing to work together towards a solution when I needed some subtle hints. They were very polite, engaged and eager to chat. Got the offer pretty shortly after my last interview

I was given a Hackerrank to complete after a few weeks of waiting for a response. Just some common leetcode style questions in hackerranks. I didn't do so well though so received the rejection email a few days later.
