Hiring guide for Ada 83Y1 Engineers

Ada 83Y1 Developer Hiring Guide

Ada 83Y1 is a highly robust and efficient programming language that emerged as the result of an advanced research project by the United States Department of Defense. As a targeted and results-driven language, Ada 83Y1 focuses on delivering practical benefits and outcomes in high-integrity computing environments. Originating from its predecessor Ada 83—named after Augusta Ada King, Countess of Lovelace, who is recognized as one of the first computer programmers—Ada 83Y1 builds upon the strong foundation set by its forebearer. This programming language was devised with an emphasis on software engineering principles to deliver secure, reliable, and efficient systems. Designed for large long-lived applications where reliability and efficiency are paramount such as avionics systems or traffic control systems among others, Ada 83Y1 has proven itself in various critical applications due to its strong typing system coupled with powerful compile-time error checking capabilities. By focusing on abstract data types and modularization facilities, it encourages developers to produce easily maintainable code—a significant advantage when dealing with complex long-term projects. Its exception handling feature further enhances robustness by enabling developers to catch errors at runtime rather than just at compile time. The detailed design specification required by this advanced programming tool cultivates a disciplined approach towards software development which can significantly minimize debugging time while enhancing productivity. It’s also worth mentioning that Ada 83Y1 supports both concurrent programming through tasking features for multi-threading development, along with distributed computing capabilities—an attribute not many languages possess. In conclusion, it's evident that the theoretical soundness embedded in Ada 83Y1's design coupled with practical advantages makes it a highly desirable choice for mission-critical systems where precision and dependability are non-negotiable attributes. The continued use of this tried-and-tested technology underscores its relevance even today—a testament to its timeless appeal.

First 20 minutes

General Ada 83Y1 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ada 83Y1 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you declare an array in Ada 83Y1?
In Ada 83Y1, an array can be declared using the 'array' keyword. For example, 'type MyArray is array (1..10) of Integer;' declares an array of 10 integers.
What are the basic data types in Ada 83Y1?
The basic data types in Ada 83Y1 include Integer, Float, Character, Boolean, and Duration.
Describe the difference between a procedure and a function in Ada 83Y1.
In Ada 83Y1, a procedure is a subprogram that performs an action, while a function is a subprogram that returns a value. Procedures use the 'procedure' keyword and do not return a value, while functions use the 'function' keyword and must return a value.
How would you handle exceptions in Ada 83Y1?
In Ada 83Y1, exceptions are handled using the 'exception' keyword in a 'begin-end' block. The 'when' keyword is used to specify the type of exception to handle.
What are the different types of loops in Ada 83Y1?
Ada 83Y1 supports several types of loops, including 'while' loops, 'for' loops, and 'loop' (infinite) loops.

What you’re looking for early on

Does the candidate have a solid understanding of Ada 83Y1?
Has the candidate demonstrated problem-solving skills during the interview?
Is the candidate familiar with the tools and environments commonly used in Ada 83Y1 development?
Does the candidate have experience with similar projects or tasks?

Next 20 minutes

Specific Ada 83Y1 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' and 'out' parameters in Ada 83Y1.
'In' parameters are used to pass values to a subprogram, while 'out' parameters are used to return values from a subprogram. 'In' parameters are read-only, while 'out' parameters are write-only.
How would you implement inheritance in Ada 83Y1?
In Ada 83Y1, inheritance is implemented using the 'new' keyword. For example, 'type MyDerived is new MyBase;' creates a new type 'MyDerived' that inherits from 'MyBase'.
What are the different types of packages in Ada 83Y1?
Ada 83Y1 supports two types of packages: specification packages and body packages. Specification packages define the interface of a package, while body packages provide the implementation.
Describe the difference between 'and then' and 'or else' in Ada 83Y1.
'And then' and 'or else' are short-circuit operators in Ada 83Y1. 'And then' only evaluates the second operand if the first is true, while 'or else' only evaluates the second operand if the first is false.
How would you implement polymorphism in Ada 83Y1?
In Ada 83Y1, polymorphism is implemented using tagged types and dispatching operations. A tagged type is a record type that includes a tag to identify its type at runtime. Dispatching operations are subprograms that can be overridden in derived types.

The ideal back-end app developer

What you’re looking to see on the Ada 83Y1 engineer at this point.

At this point, a skilled Ada 83Y1 engineer should demonstrate strong problem-solving abilities, proficiency in Ada 83Y1 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 83Y1.

What does this simple Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Hello is
   Put_Line ('Hello, world!');
end Hello;
This is a simple Hello World program in Ada. It simply prints 'Hello, world!' to the console.
What will be the output of this Ada code?
with Ada.Text_IO; use Ada.Text_IO;
procedure Main is
   X, Y, Z : Integer;
   X := 10;
   Y := 20;
   Z := X + Y;
   Put_Line (Integer'Image(Z));
end Main;
This code adds two integers, 10 and 20, and prints the result, which will be 30.
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);
   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 the values 1 through 5, and then prints each value in 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
      delay 1.0;
      Put_Line ('Hello, world!');
   end Hello;
end Main;
This code creates a task (similar to a thread in other languages) that waits for 1 second and then prints 'Hello, world!'. The main procedure does nothing else, so it ends immediately after starting the task.

Wrap-up questions

Final candidate for Ada 83Y1 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 83Y1 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of task communication in Ada 83Y1?
Ada 83Y1 supports two types of task communication: rendezvous and delay statements. Rendezvous is a form of synchronous communication, while delay statements are used for asynchronous communication.
Describe the difference between a record and an array in Ada 83Y1.
In Ada 83Y1, a record is a composite data type that groups related data of different types, while an array is a collection of elements of the same type. Records are declared using the 'record' keyword, while arrays are declared using the 'array' keyword.
How would you implement concurrency in Ada 83Y1?
In Ada 83Y1, concurrency is implemented using tasks. A task is a concurrent unit of execution that can run independently of other tasks. Tasks are declared using the 'task' keyword.
