The process started with a 90-minute OA covering two medium-to-hard level algorithm questions.

After that, I had a technical phone interview where I solved a coding problem live and explained the time and space complexity.

I also had one final round involving multiple technical interviews, each with a mix of coding and system design.

To prepare, I focused on LeetCode and also used Hack2Hire, which helped me get used to the time constraints and question style. The format was pretty close to what I saw in the actual OA.

They asked me to walk through how I would optimize a function that calculates the median of a data stream.
