The Ada 2005X5 is a high-level computer programming language, originally developed in the late 1970s by the U.S. Department of Defense to supersede over 450 programming languages used for its embedded computer systems. Named after Ada Lovelace, who is often credited as the first computer programmer, the language is designed to support large, long-lived applications where reliability and efficiency are essential. According to "Ada for Software Engineers" by Mordechai Ben-Ari, Ada's key features include strong typing, run-time checking, parallel processing, exception handling and generics. The 2005 version introduced object-oriented programming capabilities in line with modern software development practices. This version also improved real-time systems support and enhanced interoperability with other languages such as C++, as detailed in "Rationale for Ada 2005" by John Barnes.

First 20 minutes

General Ada 2005X5 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 2005X5 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?

You can declare a variable in Ada using the syntax: 'variableName : variableType;'. For example, 'x : Integer;'.

What are the basic data types in Ada?

The basic data types in Ada include Integer, Float, Character, Boolean, and others. Ada also supports more complex types like arrays, records, and enumeration types.

How would you implement exception handling in Ada?

Exception handling in Ada is done using the 'begin', 'exception', and 'when' keywords. For example, 'begin ... exception when ExceptionName => ... end;'.

What is the use of the 'with' keyword in Ada?

The 'with' keyword in Ada is used to import a package or a module. For example, 'with Ada.Text_IO;'.

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

A package in Ada is a module that can contain variables, types, procedures, and functions. A procedure, on the other hand, is a subprogram that performs a specific task.

Next 20 minutes

Specific Ada 2005X5 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 a loop in Ada?

There are several ways to implement a loop in Ada, including 'loop ... end loop;', 'while ... loop ... end loop;', and 'for ... loop ... end loop;'.

What are the different types of loops in Ada?

Ada supports several types of loops including definite loops (for), conditional loops (while), and indefinite loops (loop).

How would you define and call a procedure in Ada?

A procedure in Ada is defined using the 'procedure' keyword and it's called by its name. For example, 'procedure ProcedureName is ... end ProcedureName;' and 'ProcedureName;'.

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

The main difference between a function and a procedure in Ada is that a function returns a value and a procedure doesn't. Moreover, a function can be called in an expression, but a procedure can't.

What is the use of the 'pragma' directive in Ada?

The 'pragma' directive in Ada is used to provide additional information to the compiler, such as to disable warnings or to optimize certain parts of the code.

Oops! Something went wrong while submitting the form.

At this point, a skilled Ada 2005X5 engineer should demonstrate strong problem-solving abilities, proficiency in Ada 2005X5 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 2005X5.

What does the following Ada 2005X5 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 is the output of the following Ada 2005X5 code?
with Ada.Text_IO; use Ada.Text_IO;
procedure Show is
  Num : Integer := 10;
begin
  Put ('Num is: ' & Integer'Image(Num));
end Show;
The output is 'Num is:  10'. The code is displaying the integer value of variable 'Num'.
What does the following Ada 2005X5 code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Reverse_Array is
  type Int_Array is array (1 .. 5) of Integer;
  A : Int_Array := (1, 2, 3, 4, 5);
begin
  for I in reverse A'Range loop
    Put (Integer'Image(A(I)) & ' ');
  end loop;
end Reverse_Array;
The code prints the elements of an integer array in reverse order. The output is '5 4 3 2 1 '.
What will be the output of the following Ada 2005X5 code?
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Real_Time; use Ada.Real_Time;
procedure Show_Time is
begin
  Put_Line ('The time now is: ' & Time'Image(Clock));
end Show_Time;
The output will be the current system time when the procedure is called. The exact output will vary depending on the time of execution.

Wrap-up questions

Final candidate for Ada 2005X5 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 2005X5 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

How would you implement a recursive function in Ada?

A recursive function in Ada is implemented by having the function call itself within its own definition. For example, 'function Factorial(n : Integer) return Integer is ... return n * Factorial(n - 1); ... end Factorial;'.

What are the different types of packages in Ada?

Ada supports two types of packages: specification packages and body packages. The specification package declares the public types and subprograms, while the body package contains the implementation of these types and subprograms.

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

A task in Ada is a type of concurrent unit of execution, while a protected type is used to protect shared data from simultaneous access by multiple tasks.
