EuLisp-2.2 is a version of the EuLisp programming language, which is a dynamically-typed, object-oriented language that was designed by a group of European researchers in the late 1980s and early 1990s. The language was developed with the aim of creating a simple, efficient, and flexible Lisp-based language. EuLisp-2.2 supports multiple inheritance, generic functions, and first-class types. It also includes modules and parallel processing capabilities. The language is defined by an international standard (ISO/IEC 13751:2001) and has been used in various fields including artificial intelligence and symbolic computation.

First 20 minutes

General EuLisp-2.2 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in EuLisp-2.2 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 EuLisp-2.2?

EuLisp-2.2 is a small, flexible, and efficient language with a dynamic type system, first-class functions, lexical scoping, garbage collection, and support for object-oriented programming.

How would you define a function in EuLisp-2.2?

In EuLisp-2.2, a function is defined using the 'de' keyword followed by the function name, argument list, and the function body. For example, '(de hello-world () (print 'Hello, World!'))'.

What are the data types supported by EuLisp-2.2?

EuLisp-2.2 supports several data types including numbers, strings, symbols, lists, vectors, and user-defined types.

Describe the difference between lexical and dynamic scoping in EuLisp-2.2.

In lexical scoping, a variable's scope is determined by its position in the source code, while in dynamic scoping, the scope is determined by the program's execution context. EuLisp-2.2 primarily uses lexical scoping.

How would you handle exceptions in EuLisp-2.2?

EuLisp-2.2 provides the 'catch' and 'throw' constructs for exception handling. 'Catch' establishes a new exception handler, and 'throw' signals an exception.

Next 20 minutes

Specific EuLisp-2.2 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 is the role of the garbage collector in EuLisp-2.2?

The garbage collector in EuLisp-2.2 automatically reclaims memory that is no longer in use, freeing the programmer from the need to manually manage memory.

How would you implement object-oriented programming in EuLisp-2.2?

EuLisp-2.2 supports object-oriented programming through its class system. A class is defined using the 'defclass' construct, and methods are defined using the 'defmethod' construct.

What are the control structures provided by EuLisp-2.2?

EuLisp-2.2 provides several control structures including 'if', 'cond', 'while', 'for', 'catch', and 'throw'.

Describe the difference between 'eq' and 'equal' in EuLisp-2.2.

'Eq' tests whether two objects are the same, while 'equal' tests whether two objects are structurally equivalent. For example, two lists are 'eq' if they are the same list, but they are 'equal' if they contain the same elements.

How would you create a user-defined type in EuLisp-2.2?

In EuLisp-2.2, a user-defined type is created using the 'defclass' construct, which defines a new class with specified superclasses, slots, and methods.

Oops! Something went wrong while submitting the form.

At this point, a skilled EuLisp-2.2 engineer should demonstrate strong problem-solving abilities, proficiency in EuLisp-2.2 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 EuLisp-2.2.

What does this simple EuLisp code do?
(defun hello-world () (print 'Hello, World!'))
This code defines a function named 'hello-world' that, when called, prints the string 'Hello, World!' to the standard output.
What will be the output of this EuLisp code?
(let ((x 5) (y 10)) (+ x y))
The output of this code will be 15. It defines two local variables x and y with values 5 and 10 respectively, and then adds them together.
What does this EuLisp code do?
(defun sum-array (arr) (reduce '+ arr))
This code defines a function named 'sum-array' that takes an array as an argument and returns the sum of all elements in the array.
What does this EuLisp code do?
(defun parallel-sum (arr) (future (lambda () (reduce '+ arr))))
This code defines a function named 'parallel-sum' that takes an array as an argument and returns a future object that will eventually contain the sum of all elements in the array. The computation is done in a separate thread.

Wrap-up questions

Final candidate for EuLisp-2.2 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 EuLisp-2.2 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What is the purpose of the 'defmethod' construct in EuLisp-2.2?

The 'defmethod' construct in EuLisp-2.2 is used to define methods for classes. A method is a function that operates on objects of a certain class.

Describe the difference between 'cons', 'list', and 'vector' in EuLisp-2.2.

'Cons' creates a pair of values, 'list' creates a list of values, and 'vector' creates a vector of values. Lists and vectors are both sequences, but vectors provide constant-time access to their elements.

How would you implement recursion in EuLisp-2.2?

Recursion in EuLisp-2.2 is implemented by having a function call itself. This is commonly used for tasks such as traversing data structures or solving problems that can be broken down into smaller subproblems.
