Product Perfect

Lisp is a computer programming language created in 1958 by John McCarthy. It is a functional language with a long history and a wide range of applications. Lisp source code files are typically written in the Common Lisp dialect and contain code that can be compiled and run on a Lisp interpreter. Franz Inc. is a company that develops and sells Lisp software, including the LispWorks interpreter and the Clojure programming language.

First 20 minutes

General Lisp Source Code File (Franz Inc.) app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Lisp Source Code File (Franz Inc.) 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 Lisp?

The basic data types in Lisp include integers, floating-point numbers, characters, symbols, lists, arrays, hash-tables, and structures.

How would you define a function in Lisp?

In Lisp, a function is defined using the 'defun' keyword followed by the function name, parameters, and the function body.

What is the use of the 'car' function in Lisp?

The 'car' function in Lisp is used to return the first element of a list.

What is the role of the 'cdr' function in Lisp?

The 'cdr' function in Lisp is used to return the remainder of a list after removing the first element.

Describe the difference between 'eq' and 'equal' in Lisp.

'eq' tests whether its arguments are the same object, while 'equal' tests whether its arguments are structurally similar.

Next 20 minutes

Specific Lisp Source Code File (Franz Inc.) 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.

How would you implement recursion in Lisp?

Recursion in Lisp can be implemented by having a function call itself within its own definition.

What are the different types of variables in Lisp?

Lisp has two types of variables: lexical variables and dynamic variables.

How would you create and manipulate arrays in Lisp?

Arrays in Lisp can be created using the 'make-array' function and manipulated using the 'aref' and 'setf' functions.

What is the significance of the 'cons' function in Lisp?

The 'cons' function is used to construct new lists in Lisp.

Describe the difference between 'defun' and 'lambda' in Lisp.

'defun' is used to define a named function, while 'lambda' is used to create anonymous functions.

Oops! Something went wrong while submitting the form.

At this point, a skilled Lisp Source Code File (Franz Inc.) engineer should demonstrate strong problem-solving abilities, proficiency in Lisp Source Code File (Franz Inc.) 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 Lisp Source Code File (Franz Inc.).

What does this simple Lisp 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 Lisp code?
(let ((x 5) (y 10)) (+ x y))
The output of this code will be 15. It first binds the variables 'x' and 'y' to the values 5 and 10 respectively, and then adds these two values.
What does this Lisp code do?
(mapcar #'(lambda (x) (* x x)) '(1 2 3 4 5))
This code applies the anonymous function, which squares its input, to each element of the list (1 2 3 4 5). The result is a new list with the squares of the original list's elements.
What does this Lisp code do?
(defun parallel-execution (f g) (let ((f-thread (make-thread f)) (g-thread (make-thread g))) (join-thread f-thread) (join-thread g-thread)))
This code defines a function 'parallel-execution' that takes two functions as arguments, creates a new thread for each function, and then waits for both threads to finish execution. This allows for parallel execution of the two input functions.

Wrap-up questions

Final candidate for Lisp Source Code File (Franz Inc.) 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 Lisp Source Code File (Franz Inc.) application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

How would you handle exceptions in Lisp?

Exceptions in Lisp are handled using the 'handler-case' or 'handler-bind' functions.

What are macros in Lisp and how would you define them?

Macros in Lisp are code that writes code. They are defined using the 'defmacro' keyword.

How would you implement multi-threading in Lisp?

Multi-threading in Lisp can be implemented using the 'bt:make-thread' function from the Bordeaux-Threads library.
