Approached by a recruiter. Successfully passed all the interviews. Notified that I should wait up to 3 months to get hired. Reached out to them 3 months later. They let me know about all the new openings they had and how I should apply and start the

Recruiter interview, followed by two technical interviews. First, a coding challenge focused on data structures and algorithms. This involved a problem leveraging dictionaries for frequency counting, followed by a theoretical question about caching.

I was asked several technical and mathematical questions. I failed to find an answer to the final mathematical question. Make sure you're able to explain basic concepts such as parallelization in simple terms.
