The interview process had 4 stages:

• HackerRank test
• Interview with a recruiter (I was ghosted for about 5 weeks after applying).
• Interview with another recruiter. After this, I was sent study topics for the next interview. The interview focused mostly on streaming and a few algorithm topics.
• Live HackerRank coding test with 2 interviewers.

Coding Interview

There were 3 questions.

The first 2 questions were something similar to the HackerRank test. They had to do with aggregating streams.

The second question was related to topological sorting, ordering tasks based on dependencies. Something similar to what you'll find in a DAG.
