First 20 minutes

General Datapoint's Advanced System Language(DASL) app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Datapoint's Advanced System Language(DASL) application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

What are the key features of DASL?
DASL has several key features including object-oriented programming, exception handling, automatic memory management, and support for SQL databases.
How would you declare a variable in DASL?
In DASL, variables are declared using the 'var' keyword followed by the variable name and its type. For example, 'var x int' declares an integer variable named 'x'.
What is the use of the 'this' keyword in DASL?
In DASL, 'this' is a keyword that refers to the current instance of the class. It is used to access the methods and properties of the current object.
Describe the difference between a class and an object in DASL.
In DASL, a class is a blueprint for creating objects. It defines the properties and methods that an object will have. An object, on the other hand, is an instance of a class.
How would you handle exceptions in DASL?
In DASL, exceptions are handled using the 'try-catch' blocks. The 'try' block contains the code that might throw an exception, and the 'catch' block contains the code to handle the exception.

Describe the difference between overloading and overriding in DASL.
In DASL, overloading refers to defining multiple methods with the same name but different parameters. Overriding, on the other hand, refers to redefining a method in a subclass that is already defined in the parent class.
How would you create an instance of a class in DASL?
In DASL, an instance of a class is created using the 'new' keyword followed by the class name and any necessary parameters.
