Ada 2012X3 Developer Hiring Guide

Ada 2012X3 is a thoughtfully designed and contemplative programming language, standing as a testament to the evolution of high-level languages since its inception in the 1980s. Named after Ada Lovelace, who is often recognized as the world's first programmer, this language has continued to demonstrate its significance over time by consistently addressing the complexities of large systems. In a world increasingly dominated by technology, Ada 2012X3 provides a robust and reliable platform for developers to build and maintain critical software systems. It is a language that takes into account not only technical elements but also human factors, reflecting a deeper understanding of the dynamic interaction between humans and technology. The birth of Ada was motivated by the need for more scalable, secure, and efficient languages. This was particularly true for defense systems where reliability couldn't be compromised. From this necessity emerged a language that emphasizes clarity over brevity, safety over convenience - an ethos that has remained integral to its design philosophy. One aspect that sets Ada apart from other languages is its strong typing system which minimizes bugs and increases program reliability. The creators of Ada understood that while it may be easier to write loosely typed code initially, the long-term costs in debugging and maintaining such code can be significantly higher. Ada 2012X3 also encapsulates another deep philosophical principle: longevity. Unlike many other programming languages which are continually replaced with newer versions or altogether different technologies, Ada has been designed with an eye towards sustainability. Its specifications have been updated from time to time—Ada 95, Ada 2005, Ada 2012—but each iteration remains true to its original spirit while incorporating modern constructs and paradigms. Maintaining backward compatibility ensures that systems written in older versions of Ada can still run on newer versions without requiring extensive modifications—a nod not only towards technological efficiency but also economic sustainability. The contemplative nature of Ada's design is further reflected in its support for parallel processing and real-time systems—foresightful features at a time when multi-core processors were not yet mainstream. In summary, the thoughtful design philosophy embedded within Ada 2012X3 sets it apart from many contemporaries. It reflects an understanding that programming languages are not just tools but catalysts for progress—engines driving our economy forward while navigating through the ever-evolving technological landscape. As we continue into an age defined by digital interdependence and complex software systems, one can appreciate the profound significance of such thoughtful design principles.

First 20 minutes

General Ada 2012X3 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 2012X3 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

What are the basic data types in Ada 2012X3?
The basic data types in Ada 2012X3 include Integer, Float, Character, Boolean, Duration, and access types.
How would you define a record in Ada 2012X3?
In Ada 2012X3, a record is defined using the 'type' keyword followed by the record name, the 'record' keyword, and then the fields and their types enclosed in 'begin' and 'end' keywords.
Describe the difference between 'in', 'out', and 'in out' parameters in Ada 2012X3.
'In' parameters are used to pass values into a procedure, 'out' parameters are used to return values from a procedure, and 'in out' parameters are used for both purposes.
How would you handle exceptions in Ada 2012X3?
Exceptions in Ada 2012X3 are handled using the 'begin', 'exception', and 'when' keywords. The 'begin' block contains the code that might raise an exception, and the 'exception' block contains handlers for different exceptions.
What are the control structures in Ada 2012X3?
The control structures in Ada 2012X3 include 'if', 'case', 'loop', 'while', 'for', 'exit', 'goto', 'return', and 'null'.

Next 20 minutes

Specific Ada 2012X3 development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

How would you implement inheritance in Ada 2012X3?
Inheritance in Ada 2012X3 is implemented using the 'type' and 'new' keywords. The 'type' keyword is used to define a new type, and the 'new' keyword is used to specify the parent type.
Describe the difference between a procedure and a function in Ada 2012X3.
In Ada 2012X3, a procedure is a subprogram that performs an action, while a function is a subprogram that returns a value.
What are the visibility rules in Ada 2012X3?
In Ada 2012X3, entities are visible from the point of their declaration until the end of the scope in which they are declared. However, they are not visible within their own declaration or within the declaration of preceding entities in the same declarative part.
How would you implement polymorphism in Ada 2012X3?
Polymorphism in Ada 2012X3 is implemented using tagged types and dispatching operations. A tagged type is a record type that includes a tag for runtime type identification, and a dispatching operation is a subprogram that behaves differently depending on the tag of the object it is called with.
Describe the difference between a protected type and a task type in Ada 2012X3.
In Ada 2012X3, a protected type is a type that provides controlled access to shared data, while a task type is a type that represents a concurrent thread of control.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Ada 2012X3.

What does the following Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Hello is
   Put_Line ("Hello, world!");
end Hello;
This code prints 'Hello, world!' to the console.
What will be the output of the following Ada code?
with Ada.Text_IO; use Ada.Text_IO;
procedure Show_Sum is
   A, B, Sum : Integer;
   A := 10;
   B := 20;
   Sum := A + B;
   Put_Line (Integer'Image(Sum));
end Show_Sum;
This code will output '30' which is the sum of 10 and 20.
What does the following Ada code do?
with Ada.Text_IO; use Ada.Text_IO;

   B := A(5 .. 1 => reverse A);
   for I in B'Range loop
      Put (Integer'Image(B(I)) & ' ');
