Elevator Low Level System Design | Object Oriented Design | Elevator Algorithm
System Design | #SystemDesign :
Elevator low level system design is a common Object oriented system design problem which is asked in interviews of big tech companies like FAANG.
The over all design is simple if you consider a single elevator car but complexity increases as you add multiple elevators.
Over LLD is simple, the complex part is the algorithm for the dispatcher or scheduler unit of the elevator.
In most tech companies you might be asked just to describe the various algorithms as it might get really complicated to actually write the complete code for the scheduler in the limited time.
You might be asked to write a sudo code for one of the algorithm to check knowledge on DS and algo concept.
