Next 20 minutes

Specific EusLisp Robot Programming Language development questions

The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.

How would you create an instance of a class in EusLisp?

In EusLisp, you can create an instance of a class using the 'instance' function, followed by the class name and the initial values of the class slots.

What are the different types of methods available in EusLisp?

EusLisp provides several types of methods including instance methods, class methods, and generic functions.

How would you create a class in EusLisp?

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with EusLisp Robot Programming Language.

What does this simple EusLisp code snippet do?

(print "Hello, World!")

This code prints the string 'Hello, World!' to the standard output.

Can you explain what this EusLisp code is doing?

(setq x 5)
(setq y 10)
(+ x y)

This code first sets the value of 'x' to 5 and 'y' to 10. Then, it adds 'x' and 'y' together. The output will be 15.

What is the purpose of this EusLisp code snippet?

(setq arr (make-list 5 :initial-element 0))
(dolist (i arr) (print i))

This code creates a list with 5 elements, all initialized to 0. Then, it iterates through the list and prints each element.

What will be the output of the following EusLisp code?

(defun worker (x)
 (sleep x)
 (print x))

(dotimes (i 5)
 (threads:make-thread #'worker :arguments (list i)))

This code creates a function 'worker' that takes an argument, sleeps for that many seconds, then prints the argument. It then creates 5 threads that each run the 'worker' function with a different argument. The output will be the numbers 0 to 4 printed in an unpredictable order due to the nature of threading.

What does this EusLisp code snippet do?

(defclass person)
(setq john (instance person))
(send john :name 'John)

This code first defines a class called 'person'. Then, it creates an instance of 'person' named 'john'. Finally, it sets the 'name' property of 'john' to 'John'.

What is the purpose of the following EusLisp code?

(defun factorial (n)
  (if (<= n 1)
      1
    (* n (factorial (- n 1)))))
(factorial 5)

This code defines a recursive function to calculate the factorial of a number. It then calls this function with the argument 5. The output will be 120, which is the factorial of 5.

Wrap-up questions

Final candidate for EusLisp Robot Programming Language role questions

The final few interview questions for a EusLisp Robot Programming Language candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.

How would you perform multi-threading in EusLisp?

Multi-threading in EusLisp can be achieved using the 'make-thread' function, which creates a new thread of execution.

What are the different types of inheritance available in EusLisp?

EusLisp supports single inheritance, where a class can inherit from one superclass.

How would you implement recursion in EusLisp?

Recursion in EusLisp can be implemented by defining a function that calls itself as part of its execution.

What is the purpose of the 'apply' function in EusLisp?

'apply' is used to call a function with arguments that are contained in a list.

Describe the difference between 'let' and 'let*' in EusLisp.

'let' and 'let*' both are used to bind variables. The difference is that 'let' binds variables simultaneously, while 'let*' binds variables sequentially.
