I applied via Referral and was interviewed in Nov 2023. There was 1 interview round.
A virtual function is a function in a base class that is declared using the keyword 'virtual' and can be overridden by a function in a derived class.
Virtual functions allow a derived class to provide a specific implementation of a function that is already defined in a base class.
They enable polymorphism, where a pointer to a base class can be used to call a function in a derived class.
Virtual functions are used in obje...

CAP theorem states that in a distributed system, it is impossible to simultaneously guarantee consistency, availability, and partition tolerance.
Consistency: All nodes in the system have the same data at the same time.
Availability: Every request gets a response, even if some nodes are down.
Partition Tolerance: The system continues to operate despite network partitions.
In a distributed system, you can only achieve two o...
