Hiring guide for Ada 95X5 Engineers

Ada 95X5 Developer Hiring Guide

Ada 95X5 is a high-level, statically-typed computer programming language that emerged in the mid-1990s as an upgrade to Ada 83. This language, named after Augusta Ada Byron, Countess of Lovelace and widely considered the world's first programmer, was developed by the U.S. Department of Defense (DoD) to replace hundreds of other coding languages being used at that time ("The History of the Ada Programming Language", n.d.). The focus on safety and reliability made it particularly suited for systems where failure could have catastrophic consequences such as aviation or defense systems (Barnes, 2014). With its unique features like strong typing and support for design-by-contract, exception handling and concurrent programming ("Ada Programming/Basic", n.d.), it has been highly influential in shaping modern software engineering principles. Despite being less popular than mainstream languages today like Python or Java, Ada is still actively used in critical systems across aerospace and milita

First 20 minutes

General Ada 95X5 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 95X5 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you define the Ada 95X5 language?
Ada 95X5 is a statically typed, structured, object-oriented high-level computer programming language. It is based on Pascal and is designed for developing large, long-lived applications where reliability and efficiency are critical.
What are the key features of Ada 95X5?
Some key features of Ada 95X5 include strong typing, modularity mechanisms (packages), run-time checking, parallel processing (tasks, synchronous message passing, protected objects), exception handling, and generics.
Describe the difference between a procedure and a function in Ada 95X5.
In Ada 95X5, a procedure is a subprogram that performs an action, while a function is a subprogram that returns a value. A procedure is called for its side effects, while a function is called for its return value.
How would you handle exceptions in Ada 95X5?
In Ada 95X5, exceptions are handled using the keywords 'begin', 'exception', and 'when'. The 'begin' block contains the code that might raise an exception, the 'exception' block contains handlers for exceptions, and the 'when' keyword is used to specify different handlers for different exceptions.
What are generics in Ada 95X5 and how would you use them?
Generics in Ada 95X5 are a way to create parameterized modules or subprograms. They allow you to write code that can work with any data type. You would use them by declaring a generic with the 'generic' keyword, specifying the parameters, and then instantiating the generic with the specific types you want to use.

Next 20 minutes

Specific Ada 95X5 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 concurrency in Ada 95X5?
Concurrency in Ada 95X5 is implemented using tasks. A task is a type of module that has its own thread of control. Tasks can run in parallel and communicate with each other using entry calls, which are a form of synchronous message passing.
What are packages in Ada 95X5 and how would you use them?
Packages in Ada 95X5 are a way to group related types, variables, and subprograms. You would use them to organize your code and to control the visibility and accessibility of the entities in the package.
Describe the difference between private types and limited private types in Ada 95X5.
In Ada 95X5, a private type is a type whose full declaration is hidden from the client, but the client can still perform assignment and comparison operations on objects of the type. A limited private type is more restrictive, and does not allow assignment or comparison.
How would you implement object-oriented programming in Ada 95X5?
Object-oriented programming in Ada 95X5 is implemented using tagged types, which are similar to classes in other languages. A tagged type can have methods (subprograms associated with the type), and can be extended to create new types with additional data and methods.
What are discriminants in Ada 95X5 and how would you use them?
Discriminants in Ada 95X5 are a way to create variant records, which are records that can have different sets of components depending on the value of the discriminant. You would use them to create data structures that can represent different kinds of data.

The ideal back-end app developer

What you’re looking to see on the Ada 95X5 engineer at this point.

At this point, a skilled Ada 95X5 engineer should demonstrate strong problem-solving abilities, proficiency in Ada 95X5 programming language, and knowledge of software development methodologies. Red flags include lack of hands-on experience, inability to articulate complex concepts, or unfamiliarity with standard coding practices.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Ada 95X5.

What does the following Ada 95 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 standard output.
What will be the output of the following Ada 95 code?
with Ada.Text_IO; use Ada.Text_IO;
procedure Display_Number is
   Num : Integer := 10;
   Put ('The number is: ');
   Put (Num);
end Display_Number;
The output of this code will be 'The number is: 10'.
What does the following Ada 95 code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Array_Sum is
   type Integer_Array is array (1 .. 10) of Integer;
   Arr : Integer_Array := (others => 1);
   Sum : Integer := 0;
   for I in Arr'Range loop
      Sum := Sum + Arr(I);
   end loop;
   Put ('Sum of array elements: ');
   Put (Sum);
end Array_Sum;
This code calculates the sum of all elements in an array of 10 integers, each initialized to 1, and prints the sum, which will be 10.
What does the following Ada 95 code do?
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Real_Time; use Ada.Real_Time;
procedure Sleep_Example is
   Time : Time_Span := Milliseconds (500);
   Put_Line ('Start');
   delay until Clock + Time;
   Put_Line ('End');
end Sleep_Example;
This code prints 'Start', waits for 500 milliseconds, and then prints 'End'.

Wrap-up questions

Final candidate for Ada 95X5 Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle Ada 95X5 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

How would you implement a recursive algorithm in Ada 95X5?
A recursive algorithm in Ada 95X5 would be implemented by declaring a subprogram that calls itself. The subprogram would need to have a base case to stop the recursion, and would need to make progress towards the base case in each recursive call.
What are access types in Ada 95X5 and how would you use them?
Access types in Ada 95X5 are similar to pointers in other languages. They provide a way to refer to objects and subprograms indirectly. You would use them to create dynamic data structures, to pass large objects by reference, and to implement polymorphism.
Describe the difference between a task and a protected object in Ada 95X5.
In Ada 95X5, a task is a module that has its own thread of control and can run in parallel with other tasks. A protected object is a module that encapsulates shared data and provides synchronized access to it. Tasks are used for concurrency, while protected objects are used for mutual exclusion.
