Category interpretation:
We can be confident about this candidate's ability to implement simple logic based on the description provided. Candidate can operate on data and design simple algorithms executing specified logic. It indicates good potential for growth and becoming a professional software engineer.

Why it is relevant
While advanced knowledge of algorithms is not a necessity in the majority of real-life programming projects, all software developers should be able to understand and implement basic data structures as well as design simple algorithms processing this data according to the provided description.

Category interpretation:
Candidate has a solid practical understanding of basic fundamental concepts of object-oriented programming. Candidate is able to define objects and methods as well as use polymorphism and inheritance. Understand formal notation in the form of a UML diagram.

Why it is relevant
Object Oriented Programming is considered a fundamental design methodology for building software. In OOPS, every logic is written to get our work done and allows us to break our problems into small units of work that are represented via objects and their functions. Therefore ability to code using objects is considered a fundamental ability and is verified with the Challenge.
