Hiring guide for Ada 95X3 Engineers

Ada 95X3 Developer Hiring Guide

In the realm of computer programming languages, Ada 95X3 holds a unique and significant position. Its thoughtful design and contemplative structure reflect the deep understanding of its creators about the intricate nature of software development. Named after Ada Lovelace, widely recognized as the first computer programmer, this language carries a rich history and profound implications for the world of programming. First standardized by ANSI in 1983, Ada was initially developed by the U.S. Department of Defense to supersede hundreds of proprietary languages. The language's evolution to Ada 95X3 was marked by significant enhancements and amendments. It emerged as a high-level, statically typed, structured, imperative, and object-oriented programming language with wide-ranging applications in areas requiring high-reliability or real-time systems. The beauty of Ada 95X3 lies in its ability to encourage thoughtful programming. It is not merely a tool for instructing machines but a medium for expressing complex ideas and algorithms with clarity and precision. Its strong typing prevents many type-related bugs that are common in other languages. Moreover, its emphasis on software engineering principles such as modularity, encapsulation, and information hiding promotes maintainability and reusability. Ada 95X3's design principles are rooted in the desire to minimize unpredictable behavior - an essential quality for safety-critical systems. This is achieved through features like exception handling and concurrency control that ensure reliable execution even under adverse conditions. Reflecting on the deeper implications of Ada 95X3 reveals its significance beyond just being a programming language. It represents a philosophy that values robustness, reliability, maintainability, and efficiency. In essence, it emphasizes that effective communication with machines is not just about issuing commands but involves articulating ideas with precision and care. Ada 95X3's influence extends beyond its immediate applications. Its principles have inspired many modern programming languages and continue to shape our understanding of good software design practices. As we delve deeper into the age of digitalization, Ada 95X3 stands as a testament to the power of thoughtful design and serves as a beacon guiding us towards creating more reliable and efficient software systems.

First 20 minutes

General Ada 95X3 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 95X3 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you declare a variable in Ada 95X3?
To declare a variable in Ada 95X3, you would use a declaration statement. For example, 'Var : Integer;' declares a variable named Var of type Integer.
What are the basic data types in Ada 95X3?
The basic data types in Ada 95X3 are Integer, Float, Character, Boolean, and Duration.
Describe the difference between a function and a procedure in Ada 95X3.
In Ada 95X3, a function is a subprogram that returns a value, while a procedure is a subprogram that does not return a value.
How would you handle exceptions in Ada 95X3?
In Ada 95X3, exceptions are handled using the 'begin', 'exception', and 'when' keywords. You can define your own exceptions and raise them using the 'raise' keyword.
What are the control structures available in Ada 95X3?
The control structures available in Ada 95X3 are sequence, selection (if and case), and iteration (loop, while, and for).

Next 20 minutes

Specific Ada 95X3 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.

Describe the difference between 'in' and 'out' parameters in Ada 95X3.
In Ada 95X3, 'in' parameters are used to pass values to a subprogram, while 'out' parameters are used to return values from a subprogram. 'In' parameters are read-only, while 'out' parameters are write-only.
How would you implement polymorphism in Ada 95X3?
In Ada 95X3, polymorphism is implemented using tagged types and type extension. A tagged type is a record type that includes a tag, which identifies the type and its extensions.
What are the different types of packages in Ada 95X3?
In Ada 95X3, there are two types of packages: specification packages and body packages. Specification packages declare the public types, variables, and subprograms, while body packages provide the implementation of the subprograms declared in the specification package.
Describe the difference between a record and an array in Ada 95X3.
In Ada 95X3, a record is a collection of variables of different types, while an array is a collection of variables of the same type. Records are similar to structs in C, while arrays are similar to arrays in other languages.
How would you implement multithreading in Ada 95X3?
In Ada 95X3, multithreading is implemented using tasks. A task is a type of object that has its own thread of control, and tasks can run concurrently with each other.

The ideal back-end app developer

What you’re looking to see on the Ada 95X3 engineer at this point.

At this point, a skilled Ada 95X3 engineer should demonstrate strong problem-solving abilities, proficiency in Ada 95X3 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 95X3.

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 the string 'Hello, world!' to the standard output.
What will be the output of the following Ada 95 code snippet?
with Ada.Text_IO; use Ada.Text_IO;
procedure Main is
  X, Y, Z : Integer := 10;
  Z := X + Y;
  Put_Line (Integer'Image(Z));
end Main;
The output of this code will be '20'. The code declares three integers X, Y, and Z, initializes X and Y to 10, then adds X and Y and assigns the result to Z. It then prints the value of Z.
What does the following Ada 95 code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Main is
  type Array_Type is array (1 .. 5) of Integer;
  Arr : Array_Type := (others => 0);
  for I in Arr'Range loop
    Arr (I) := I * 10;
    Put_Line (Integer'Image(Arr (I)));
  end loop;
end Main;
This code creates an array of five integers, initializes them all to zero, then assigns to each element the value of its index times 10. It prints each value as it is assigned.
What does the following Ada 95 code do?
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Task_Identification;
procedure Main is
  Task_Id : Ada.Task_Identification.Task_Id := Ada.Task_Identification.Current_Task;
  Put_Line ('Current task ID: ' & Ada.Task_Identification.Image (Task_Id));
end Main;
This code prints the ID of the current task. It uses the 'Current_Task' function from the 'Ada.Task_Identification' package to get the ID of the current task, then prints it.

Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of loops in Ada 95X3?
In Ada 95X3, there are three types of loops: while loops, for loops, and loop statements. While loops repeat until a condition is false, for loops repeat for a specified number of times, and loop statements repeat indefinitely until a 'exit' statement is encountered.
Describe the difference between a private type and a limited private type in Ada 95X3.
In Ada 95X3, a private type is a type whose implementation details are hidden, but can be copied and compared for equality. A limited private type is similar, but cannot be copied or compared for equality.
How would you implement inheritance in Ada 95X3?
In Ada 95X3, inheritance is implemented using type extension. A new type can be declared as an extension of an existing type, and it inherits all the components and operations of the existing type.
