PepsiCo interview questions

1st round of the previous project architecture discussion and coding problem-solving. You are building a simplified air traffic monitoring system that tracks multiple aircraft in 3D space and detects potential conflicts between them. Each aircraft (flight) is defined by: A unique Flight ID Latitude and Longitude (in degrees) Altitude (in meters above sea level) Speed (in meters per second) Heading (in degrees, where 0° = North, 90° = East) Simulate the movement of all flights over a given time interval and detect conflicts, where two flights come closer than a minimum safe separation distance. 2nd round system design 3rd onsite face-to-face discussion on the previous project, followed by a coding round focused on Java Spring Boot. Develop rest services with business logic and write unit tests.
