Hiring guide for Ada 83Z1 Engineers

Ada 83Z1 Developer Hiring Guide

Immerse yourself in the world of Ada 83Z1, a programming language that is akin to the classic literature of the tech world. It is a language steeped in history, tracing its roots back to the late 1970s when the Department of Defense (DoD) felt an urgent need for a high-level programming language that would supersede the hundreds of other languages in use. Ada 83Z1 emerged as a beacon of hope from this chaos, named after Augusta Ada King, Countess of Lovelace and deemed by many as the first programmer ever. Ada 83Z1 is like an intricate tapestry woven with threads of precision and reliability. It was crafted with an emphasis on software engineering principles and is often compared to a master architect meticulously designing structures that are both robust and elegant. It's not merely about writing code; it's about crafting software with finesse and accuracy. Anecdotes abound about Ada 83Z1's significant role in real-time systems. An instance worth mentioning is its widespread usage in avionics. Imagine an Airbus A340 soaring through the skies, its flight control system guided by millions of lines of Ada code. Or consider NASA’s space shuttles, where Ada has been at the helm, navigating these colossal machines through the vast expanse of space. What sets Ada 83Z1 apart from other programming languages is its strong typing system designed to catch errors at compile time rather than runtime, akin to having a vigilant sentinel standing guard against potential threats. This feature dramatically reduces debugging time and leads to more reliable software - a factor that has made it immensely popular in mission-critical systems where failure could have catastrophic consequences. The language also features modularity which allows for separate compilation and fosters code reuse - much like using building blocks to construct more complex structures while retaining individual block integrity. This enhances maintainability and makes it easier for teams to work collaboratively on large projects without stepping on each other’s toes. Though some may argue that Ada 83Z1 seems verbose or rigid compared to modern languages like Python or Ruby, proponents might counter-argue that it's this very rigidity that ensures reliability and safety – much like how strict laws help maintain order in society. In conclusion, while newer programming languages may have eclipsed Ada 83Z1 in terms of popularity or ease-of-use, none can deny its historical significance or undervalue its continued relevance in sectors where precision and dependability are paramount. Like an old grandmaster chess player, it continues to hold its own amidst newer competitors – offering wisdom gleaned from decades of experience coupled with uncompromising discipline.

First 20 minutes

General Ada 83Z1 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 83Z1 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 83Z1 programming language?
Ada 83Z1 is a statically typed, structured, imperative, and object-oriented high-level computer programming language, extended from Pascal and other languages. It was originally designed by the United States Department of Defense in the late 1970s to supersede the hundreds of programming languages then in use by the defense contractor community.
What are the key features of Ada 83Z1?
Ada 83Z1 has strong typing, modules, run-time checking, parallel processing, exception handling, and generics. It also supports object-oriented programming, distributed programming, and real-time programming.
Describe the difference between Ada 83Z1 and other programming languages.
Ada 83Z1 is designed for large, long-lived applications where reliability and efficiency are essential, particularly real-time and embedded systems. It has built-in language support for design-by-contract, extremely strong typing, explicit concurrency, tasks, synchronous message passing, protected objects, and non-determinism.
How would you handle exception in Ada 83Z1?
In Ada 83Z1, exceptions are handled using the keywords 'begin', 'exception', and 'when'. The 'begin' block contains the code that might raise an exception, and the 'exception' block contains handlers for exceptions. Each handler is introduced by the 'when' keyword followed by an exception name.
What are the data types available in Ada 83Z1?
Ada 83Z1 provides several data types including Integer, Float, Character, Boolean, Duration, String, and user-defined types.

Next 20 minutes

Specific Ada 83Z1 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 define a procedure in Ada 83Z1?
A procedure in Ada 83Z1 is defined using the 'procedure' keyword followed by the procedure name, a list of parameters enclosed in parentheses, and 'is' keyword. The procedure body is enclosed between 'begin' and 'end' keywords.
Describe the difference between a function and a procedure in Ada 83Z1.
In Ada 83Z1, a function is a subprogram that returns a value, while a procedure is a subprogram that performs an action and does not return a value.
What are the control structures available in Ada 83Z1?
Ada 83Z1 provides several control structures including sequence, selection (if and case), and repetition (loop, while, and for).
How would you implement concurrency in Ada 83Z1?
Concurrency in Ada 83Z1 is implemented using tasks. A task is a type of module that has its own thread of control, allowing it to execute concurrently with other tasks.
What are the access types in Ada 83Z1?
Access types in Ada 83Z1 are similar to pointers in other languages. They provide a way to create dynamic data structures like linked lists and trees.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Ada 83Z1.

What does this simple Ada 83Z1 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 does this Ada 83Z1 code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Show_Sum is
  A, B, Sum : Integer;
  A := 5;
  B := 10;
  Sum := A + B;
  Put_Line (Integer'Image(Sum));
end Show_Sum;
This code declares three integers A, B, and Sum. It assigns 5 to A, 10 to B, and the sum of A and B to Sum. Then it prints the value of Sum, which is 15.

  Sum : Integer := 0;
  for I in Array_Var'Range loop
    Sum := Sum + Array_Var(I);
  end loop;
  Put_Line (Integer'Image(Sum));
end Array_Sum;
This code declares an array of 5 integers and initializes it with the values 1 to 5. It then calculates the sum of all elements in the array and prints the sum, which is 15.
