**Ada 2012** is a modern programming language designed for safety-critical and high-reliability systems. It is named after Ada Lovelace, an English mathematician and writer who is considered the first computer programmer. Ada was developed by the United States Department of Defense in the 1970s and 1980s, and it was standardized by the International Organization for Standardization (ISO) in 1983. The latest version of Ada, Ada 2012, was published in 2012. Ada is a general-purpose language that can be used to develop a wide variety of applications, including operating systems, embedded systems, and real-time systems. It is known for its safety features, which include built-in array bounds checking and exception handling. Ada is also a strongly typed language, which means that it prevents errors caused by type mismatches. Ada is used by a variety of organizations, including NASA, the U.S. Department of Defense, and the European Space Agency. It is also used by a number of commercial co

First 20 minutes

General Ada 2012Y5 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 2012Y5 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 2012Y5?

In Ada, a variable is declared using the syntax: 'variable_name : type := initial_value;' For example, 'counter : Integer := 0;'

What are the basic data types in Ada 2012Y5?

The basic data types in Ada include integer types, floating point types, fixed point types, enumeration types, character types, boolean types, and access types.

Describe the difference between a procedure and a function in Ada 2012Y5.

A procedure is a subprogram that performs actions, while a function is a subprogram that returns a value. Procedures do not have a return statement, whereas functions must have a return statement.

How would you implement exception handling in Ada 2012Y5?

Exception handling in Ada is implemented using the keywords 'begin', 'exception', 'when', 'raise', and 'others'. The code that might raise an exception is placed after 'begin', and the handling code is placed after 'exception'.

What are the different types of loops in Ada 2012Y5?

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

What you’re looking for early on

Has the candidate demonstrated a strong understanding of Ada 2012Y5?

Did the candidate show experience with software development methodologies?

Has the candidate shown problem-solving skills and the ability to think logically?

Did the candidate express good communication skills?

Next 20 minutes

Specific Ada 2012Y5 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 a package and a procedure in Ada 2012Y5.

A package is a module that can contain any Ada object, including procedures, whereas a procedure is a subprogram that performs actions. A package is used to group related objects together and can contain one or more procedures.

How would you implement concurrency in Ada 2012Y5?

Concurrency in Ada is implemented using tasks. Tasks are similar to threads in other languages and can execute concurrently with other tasks.

What are the different types of arrays in Ada 2012Y5?

Ada provides two types of arrays: one-dimensional arrays and multi-dimensional arrays. One-dimensional arrays have a single index, whereas multi-dimensional arrays have multiple indices.

Describe the difference between a record and an array in Ada 2012Y5.

A record is a composite data type that groups related data of different types, whereas an array is a collection of elements of the same type. Records are similar to structs in C, and arrays are similar to arrays in other languages.

How would you implement object-oriented programming in Ada 2012Y5?

Object-oriented programming in Ada is implemented using tagged types, which are similar to classes in other languages. Tagged types can have methods, which are subprograms that operate on objects of the tagged type.

Oops! Something went wrong while submitting the form.

At this point, a skilled Ada 2012Y5 engineer should demonstrate strong problem-solving abilities, proficiency in Ada 2012Y5 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 2012Y5.

What does the following 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 the following Ada code?
with Ada.Text_IO; use Ada.Text_IO;
procedure Show_Sum is
   A, B, Sum : Integer;
begin
   A := 10;
   B := 20;
   Sum := A + B;
   Put_Line (Integer'Image(Sum));
end Show_Sum;
The output of this code will be '30'. The code adds two integers A and B and prints the sum.
What does the following Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Reverse_Array is
   type Array_Type is array (1 .. 5) of Integer;
   Array1 : Array_Type := (1, 2, 3, 4, 5);
   Array2 : Array_Type;
begin
   Array2 := Array1(5 downto 1);
   for I in Array2'Range loop
      Put (Integer'Image(Array2(I)) & " ");
   end loop;
end Reverse_Array;
This code reverses an array of integers and prints the reversed array.
What does the following Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Real_Time; use Ada.Real_Time;
procedure Delay_Example is
   Time_Start : Time;
begin
   Time_Start := Clock;
   delay 1.0;
   Put_Line (Duration'Image(Clock - Time_Start));
end Delay_Example;
This code introduces a delay of 1 second and prints the actual time elapsed, demonstrating Ada's concurrency capabilities.

Wrap-up questions

Final candidate for Ada 2012Y5 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 2012Y5 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of access types in Ada 2012Y5?

Ada provides two types of access types: general access types and pool-specific access types. General access types can designate any object of a specific type, whereas pool-specific access types can only designate objects allocated in a specific storage pool.

Describe the difference between a task and a protected type in Ada 2012Y5.

A task is a type that defines a concurrent unit of execution, whereas a protected type is a type that provides controlled concurrent access to its data. Tasks are similar to threads, and protected types are similar to monitors in other languages.

How would you implement generics in Ada 2012Y5?

Generics in Ada are implemented using the 'generic' keyword. A generic is a template for a package, subprogram, or type that can be instantiated with different types.
