Ada 2005X1 is a high-level, structured, statically typed programming language that offers modularity, encapsulation, genericity and exception handling. It was developed under the auspices of the United States Department of Defense during the late 1970s and early 1980s as a part of its High Order Language Working Group (HOLWG). The purpose was to supersede over hundreds of proprietary languages used by DoD at that time with a single efficient language. The Ada programming language has been named after Augusta Ada King-Noel, Countess of Lovelace widely recognized as one of the first computer programmers for her work on Charles Babbage's proposed mechanical general-purpose computer – the Analytical Engine. The specific variant being discussed here - Ada 2005X1 - represents an enhanced version released in 2005 which included interfaces to other languages like C++, Java and Fortran; improved object-oriented programming support; additional real-time features; increased security capabilities along with other modifications beneficial for large-scale system implementation. Given its rigorous design principles aimed at safety-critical systems development such as avionics software and defense systems where reliability is paramount, it comes as no surprise that it finds significant usage in sectors including aerospace & defense industries. Notably distinct about Ada is its strong typing mechanism designed to catch errors early during compile-time rather than run-time thus enhancing code safety & robustness. Moreover, it employs an innovative package construct allowing for information hiding which bolsters modularization & maintainability reducing overall software development costs in long-term projects. Furthermore,it has extensive facilities for handling concurrency (the execution of several tasks simultaneously), through tasking capabilities built into the language syntax itself making it particularly suited for real-time applications requiring deterministic response times & predictability Overall,the systematic approach embedded within ADA's design philosophy makes this high-level programing tool an asset when applied towards large scale projects involving critical operations where failure isn't an option.

First 20 minutes

General Ada 2005X1 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 2005X1 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you describe the structure of an Ada program?

An Ada program is structured into packages, procedures and functions. Packages are the primary means of encapsulating related declarations and functionalities. Procedures and functions are used to define actions and calculations.

What are the basic data types in Ada?

The basic data types in Ada include Integer, Float, Character, Boolean, Duration, and access types.

Describe the difference between a procedure and a function in Ada.

In Ada, a procedure is a subprogram that performs an action, but does not return a value. On the other hand, a function is a subprogram that performs a computation and returns a value.

How would you handle exceptions in Ada?

In Ada, exceptions are handled using the keywords 'begin', 'exception', and 'when'. When an exception is raised, control is transferred to the exception handler, which is specified in the 'when' clause.

What are the uses of packages in Ada?

Packages in Ada are used to encapsulate related declarations and functionalities. They help in organizing the code, improving maintainability and reusability.

What you’re looking for early on

Does the candidate have a strong understanding of Ada 2005X1?

Has the candidate demonstrated problem-solving skills during the interview?

Is there evidence of the candidate's ability to work in a team?

Has the candidate shown a willingness to learn and adapt?

Next 20 minutes

Specific Ada 2005X1 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', 'out', and 'in out' parameters in Ada.

'In' parameters are used to pass values to a subprogram, 'out' parameters are used to return values from a subprogram, and 'in out' parameters are used for both purposes.

How would you implement concurrency in Ada?

Concurrency in Ada is implemented using tasks. A task is a type of concurrent unit of execution. Ada also provides protected types for mutual exclusion and condition synchronization.

What are the different types of loops in Ada?

Ada provides several types of loops, including the while loop, for loop, and loop (equivalent to a do-while loop in other languages).

Describe the difference between a task and a protected type in Ada.

A task in Ada is a unit of concurrent execution, while a protected type is a data structure that provides built-in mutual exclusion, allowing safe access from multiple tasks.

How would you create a generic package in Ada?

A generic package in Ada is created using the 'generic' keyword, followed by a list of generic formal parameters. The body of the package defines the operations on these parameters.

Oops! Something went wrong while submitting the form.

At this point, a skilled Ada 2005X1 engineer should demonstrate strong problem-solving abilities, proficiency in Ada 2005X1 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 2005X1.

What does this simple Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Hello is
begin
   Put_Line ("Hello, world!");
end Hello;
This code prints 'Hello, world!' to the standard output.
What will be the output of this Ada code?
with Ada.Text_IO; use Ada.Text_IO;
procedure Main is
   X : Integer := 10;
   Y : Integer := 20;
begin
   Swap (X, Y);
   Put_Line (Integer'Image (X));
   Put_Line (Integer'Image (Y));
end Main;
procedure Swap (A, B : in out Integer) is
   Temp : Integer;
begin
   Temp := A;
   A := B;
   B := Temp;
end Swap;
The output of this code will be '20' and '10'. The code swaps the values of X and Y using the Swap procedure.
What does this Ada code do with an array?
with Ada.Text_IO; use Ada.Text_IO;
procedure Main is
   type Array_Type is array (1 .. 5) of Integer;
   Array_Var : Array_Type := (1, 2, 3, 4, 5);
begin
   for I in Array_Var'Range loop
      Put_Line (Integer'Image (Array_Var (I)));
   end loop;
end Main;
This code declares an array of 5 integers, initializes it with values from 1 to 5, and then prints each element of the array.
What does this Ada code do related to threading?
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Real_Time; use Ada.Real_Time;
with Ada.Task_Identification;
procedure Main is
   task Hello;
   task body Hello is
   begin
      delay 1.0;
      Put_Line ("Hello, world!");
   end Hello;
begin
   null;
end Main;
This code creates a task that waits for 1 second and then prints 'Hello, world!'. The main procedure does nothing.

Wrap-up questions

Final candidate for Ada 2005X1 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 2005X1 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the rules for overloading operators in Ada?

In Ada, operators can be overloaded by declaring a function with the operator symbol as its name. The function must have at least one parameter of the type for which the operator is being overloaded.

Describe the difference between a limited type and a non-limited type in Ada.

A limited type in Ada is a type that does not allow assignment or equality operations. On the other hand, a non-limited type allows these operations.

How would you implement polymorphism in Ada?

Polymorphism in Ada is implemented using tagged types and class-wide types. A tagged type is a record type that includes a tag to identify its type at runtime. A class-wide type represents a class of types including a tagged type and all of its derivatives.
