Ada 2012X5 Developer Hiring Guide

The Ada 2012X5 is an advanced version of the high-level computer programming language, Ada, which was originally developed in the late 1970s by the U.S. Department of Defense (DoD). This iteration was standardized by ISO in December 2012 and it introduced contract-based programming and multicore support to enhance software reliability. The language's name honors Augusta Ada King-Noel, Countess of Lovelace who is often credited as one of history's first programmers due to her work on Charles Babbage’s early mechanical general-purpose computer. It has been widely used for critical systems where safety and security are paramount such as avionics and defense projects (source: "Ada Programming Language", Encyclopedia Britannica). With its strong typing system, run-time checking features among others; it continues to be a preferred choice for developing large-scale software systems.

Ask the right questions secure the right Ada 2012X5 talent among an increasingly shrinking pool of talent.

First 20 minutes

General Ada 2012X5 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 2012X5 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

What are the key features of Ada 2012X5?
Ada 2012X5 includes features such as strong typing, modularity, run-time checking, parallel processing, exception handling, and generics.
How would you handle exceptions in Ada 2012X5?
In Ada 2012X5, 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 various exceptions.
Describe the difference between strong typing and weak typing in the context of Ada 2012X5.
Strong typing in Ada 2012X5 means that the type of a variable is checked at compile time. This can prevent many programming errors. Weak typing, on the other hand, allows more flexibility but can lead to runtime errors.
What are generics in Ada 2012X5 and how would you use them?
Generics in Ada 2012X5 are a way to create reusable code. You can create a generic package or procedure, and then instantiate it with different types.
How would you implement parallel processing in Ada 2012X5?
Parallel processing in Ada 2012X5 can be implemented using tasks. Tasks in Ada are like threads in other languages, and can run concurrently.

Next 20 minutes

Specific Ada 2012X5 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.

What are the benefits of using modularity in Ada 2012X5?
Modularity in Ada 2012X5 allows for better organization of code, easier maintenance, and reusability. It also helps in managing complexity of large software systems.
Describe the difference between a procedure and a function in Ada 2012X5.
In Ada 2012X5, a procedure is a subprogram that performs an action, while a function is a subprogram that returns a value. A procedure does not have a return statement, while a function must have one.
How would you use the 'with' clause in Ada 2012X5?
The 'with' clause in Ada 2012X5 is used to import a package into the current scope. It's similar to the 'import' statement in other languages.
What are the uses of 'pragma' in Ada 2012X5?
In Ada 2012X5, 'pragma' is used to provide additional information to the compiler, such as compiler directives or special processing instructions.
How would you implement data abstraction in Ada 2012X5?
Data abstraction in Ada 2012X5 can be implemented using private types and packages. The private type hides the implementation details, and the package provides the interface.

The ideal back-end app developer

What you’re looking to see on the Ada 2012X5 engineer at this point.

At this point, a skilled Ada 2012X5 engineer should demonstrate strong problem-solving abilities, proficiency in Ada 2012X5 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 2012X5.

What does this 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 will be the output of this code?
with Ada.Text_IO; use Ada.Text_IO;
procedure Display_Number is
X : Integer := 10;
Put (Item => X, Fore => 1, Aft => 2, Exp => 0);
end Display_Number;
This code will output '10.00'. The Put procedure is used to display the value of X with 1 digit before the decimal point and 2 digits after the decimal point.
What does this code do?
with Ada.Containers.Vectors;
procedure Array_Manipulation is
package Integer_Vectors is new Ada.Containers.Vectors (Index_Type => Natural, Element_Type => Integer);
V : Integer_Vectors.Vector;
Integer_Vectors.Append (Container => V, New_Item => 2);
end Array_Manipulation;
This code creates a Vector V of integers and appends the integer 2 to the vector.
What does this code do?
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Real_Time; use Ada.Real_Time;
procedure Concurrency is
task T1 is
entry Start;
end T1;
task body T1 is
Put_Line ("Task T1 started");
end T1;
end Concurrency;
This code creates a concurrent task T1. When the task is started, it prints 'Task T1 started' to the standard output.

Wrap-up questions

Final candidate for Ada 2012X5 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 2012X5 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the differences between 'in', 'out', and 'in out' parameters in Ada 2012X5?
'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.
How would you use the 'for' loop in Ada 2012X5?
The 'for' loop in Ada 2012X5 is used to repeat a block of code a specific number of times. The loop parameter takes on each value in a given range, and the loop body is executed for each value.
Describe the difference between a task and a protected object in Ada 2012X5.
In Ada 2012X5, a task is a concurrent unit of execution, while a protected object is used for synchronization and communication between tasks.
