PayPal Role Specialization Round and Low-Level
Design Round Questions
PayPal asks LLD question in their role specialization round many times. So, if a role specialization round is scheduled then confirm with recruiter whether this will be a LLD round.
There can be multiple LLD rounds or a mix of LLD+HLD round.
Some HLD rounds may have questions like design LRU cache or design parking lot, ticket booking system etc. These start with basic low level implementation (e.g. using HashMap and Doubly Linked List in case of LRU cache) and then move to scaling the whole thing.
