I applied through a recruiter. The process took 3 weeks.

I applied through a recruiter, she was very prompt in her responses and made sure I knew everything I needed to know before each round. There were 4 technical rounds and 1 HR round. Round 1 was a general screening round which dealt with questions related to current work and a problem at the end. Round 2 was a coding assessment round. Rounds 3 and 4 were again based on system design and building scalable architectures.

They had in depth discussion regarding current project and the ways it can be enhanced. Both asked a problem at the end. HR round was a culture fitment round which mostly had behavioural questions.

How would you scale any one of your projects for millions of users?

There were questions regarding architecture and tech stack decisions that went into building the project.
