Ada 2012Y2 Developer Hiring Guide

Ada 2012Y2 is not a recognized programming language. It seems like there might be some confusion in the naming. Ada is a structured, statically typed, high-level computer programming language that was originally designed by the U.S Department of Defense in the late 1970s to supersede over 450 programming languages used for its embedded systems. The latest version of this language is Ada 2012. However, "2012Y2" does not correspond to any known version or variant of Ada. If you're referring to a specific implementation or extension of Ada, it would be best to check with your source for more accurate information.

Ask the right questions secure the right Ada 2012Y2 talent among an increasingly shrinking pool of talent.

First 20 minutes

General Ada 2012Y2 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 2012Y2 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

What are the basic data types in Ada 2012Y2?
The basic data types in Ada 2012Y2 include Integer, Float, Character, Boolean, and Duration.
How would you declare a variable in Ada 2012Y2?
In Ada 2012Y2, you declare a variable by specifying its name, followed by a colon and then its type. For example, 'Var: Integer;' declares a variable named 'Var' of type Integer.
What is the purpose of 'with' clause in Ada 2012Y2?
The 'with' clause in Ada 2012Y2 is used to import a package or a module into the current scope. It is similar to the 'import' statement in other languages.
Describe the difference between a procedure and a function in Ada 2012Y2.
In Ada 2012Y2, a procedure is a subprogram that performs an action, while a function is a subprogram that returns a value. A procedure does not return a value directly, whereas a function does.
How would you handle exceptions in Ada 2012Y2?
In Ada 2012Y2, exceptions are handled using the 'begin', 'exception', and 'when' keywords. You write the code that might raise an exception inside a 'begin' block, and then handle the exception in an 'exception' block using 'when'.

Next 20 minutes

Specific Ada 2012Y2 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 different types of loops in Ada 2012Y2?
Ada 2012Y2 supports several types of loops, including 'while' loops, 'for' loops, and 'loop' loops. 'While' loops execute as long as a condition is true, 'for' loops iterate over a range of values, and 'loop' loops execute indefinitely until an 'exit' statement is encountered.
How would you define a record in Ada 2012Y2?
In Ada 2012Y2, a record is defined using the 'type' keyword followed by the record name, the 'record' keyword, and then the fields of the record. Each field is declared like a variable, with a name and a type.
What is the use of 'pragma' in Ada 2012Y2?
In Ada 2012Y2, 'pragma' is used to provide additional information to the compiler, such as compiler directives or special processing instructions. It can be used to control aspects of the program's compilation.
Describe the difference between 'in' parameters and 'out' parameters in Ada 2012Y2.
In Ada 2012Y2, 'in' parameters are used to pass values into a subprogram, while 'out' parameters are used to return values from a subprogram. 'In' parameters are read-only within the subprogram, while 'out' parameters can be modified.
How would you implement concurrency in Ada 2012Y2?
Concurrency in Ada 2012Y2 is implemented using tasks. A task is a type of object that runs concurrently with other tasks. You can define a task using the 'task' keyword, and you can control the execution of tasks using 'entry', 'accept', 'select', and 'delay' statements.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Ada 2012Y2.

What does the following Ada code do?
procedure Hello is
  Put_Line ("Hello, World!");
end Hello;
This code prints the string 'Hello, World!' to the console.
What will be the output of the following Ada code?
procedure Add is
  A, B, C : Integer;
  A := 5;
  B := 10;
  C := A + B;
  Put_Line (Integer'Image(C));
end Add;
This code will output the sum of A and B, which is 15.
What does the following Ada code do?
procedure Array_Sum is
  type Int_Array is array (1 .. 5) of Integer;
  A : Int_Array := (1, 2, 3, 4, 5);
  Sum : Integer := 0;
  for I in A'Range loop
    Sum := Sum + A(I);
  end loop;
  Put_Line (Integer'Image(Sum));
end Array_Sum;
This code calculates the sum of all elements in the array A and prints the sum, which is 15.
What does the following Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Real_Time; use Ada.Real_Time;
procedure Delayed_Print is
  task type Delayed_Task (Delay : Time_Span);
  task body Delayed_Task is
    delay Delay;
    Put_Line ("Delayed print");
  end Delayed_Task;
  D : Delayed_Task := Delayed_Task (Seconds (5));
end Delayed_Print;
This code creates a task that waits for a specified amount of time (5 seconds in this case) before printing 'Delayed print' to the console.

Wrap-up questions

Final candidate for Ada 2012Y2 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 2012Y2 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of arrays in Ada 2012Y2?
Ada 2012Y2 supports two types of arrays: one-dimensional arrays and multi-dimensional arrays. One-dimensional arrays have a single index, while multi-dimensional arrays have multiple indices.
Describe the difference between a private type and a limited private type in Ada 2012Y2.
In Ada 2012Y2, a private type is a type whose full definition is hidden from clients, while a limited private type is a private type that also restricts assignment and comparison. Clients can only interact with these types through the operations defined in the package specification.
How would you implement inheritance in Ada 2012Y2?
Inheritance in Ada 2012Y2 is implemented using tagged types. A tagged type is a record type that includes a tag, which identifies the type. You can define a new type that inherits from a tagged type using the 'new' keyword and the 'with' keyword.
