Online assessment: Discussed increasing subsequences and priority queues. The assessment was math-heavy, more so than algorithmic, and required thinking outside the box. I spoke with a recruiter and was assigned an OA for a mid-level position.

This was a coding question, discussing technologies for a project. I talked about complex technology issues I encountered and how I solved them. The coding question was of average difficulty, and the entire interview took one and a half hours.

Four 45-minute rounds with a 15-minute break between each round, totaling 5 hours. Three rounds are for coding, and one is for system design. Each interview consists of 20 minutes of behavioral questions and 30 minutes of technical parts.
