Hiring guide for Cecil (programming language) Engineers

Cecil (programming language) Developer Hiring Guide

Cecil is a purely object-oriented programming language that was developed in the early 1990s at the University of Washington. It is noted for its flexible and efficient dynamic dispatch mechanism, which supports multimethods and subtype polymorphism. Cecil also includes mechanisms for safe type inference, delegation-based inheritance, separate implementation and type hierarchies, garbage collection support, multiple return values among others. The design philosophy behind Cecil was to create a language that would provide advanced features needed by sophisticated software systems while still being simple enough to be easily learned and used by novice programmers. The creators of Cecil aimed to combine the best elements from several other languages including C++, Smalltalk, Modula-3 etc., resulting in an expressive yet efficient programming tool. However it's worth noting that despite its innovative features at the time of development; today it's not widely used or known outside academic circles due to emergence of more popular languages with similar capabilities such as Python or Ruby.

First 20 minutes

General Cecil (programming language) app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Cecil (programming language) 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 the Cecil programming language?
Cecil includes features such as dynamic typing, multiple dispatch, a classless object model, delegation, and a flexible static scope rule for names.
How would you define a method in Cecil?
In Cecil, a method is defined using the 'method' keyword, followed by the method name, parameters, and the method body enclosed in curly braces.
What is the role of delegation in Cecil?
Delegation in Cecil is a mechanism by which an object can delegate some of its responsibilities to another object.
Describe the difference between static and dynamic typing in Cecil.
Static typing checks the types at compile-time, while dynamic typing checks the types at runtime. Cecil supports dynamic typing.
How would you handle exceptions in Cecil?
Cecil does not have built-in exception handling. However, you can implement your own exception handling mechanism using conditionals and method calls.

Next 20 minutes

Specific Cecil (programming language) 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 purpose of multiple dispatch in Cecil?
Multiple dispatch in Cecil allows a method to be selected based on the runtime types of all its arguments, not just the receiver.
How would you implement inheritance in Cecil?
Cecil does not support inheritance in the traditional sense. Instead, it uses a prototype-based model where objects can delegate responsibilities to other objects.
What are the advantages of using Cecil over other programming languages?
Advantages of Cecil include its support for dynamic typing, multiple dispatch, and a classless object model, which can make it more flexible and expressive than some other languages.
How would you create an object in Cecil?
In Cecil, you can create an object by calling a constructor method, which returns a new object.
Describe the difference between a class-based and a classless object model in Cecil.
In a class-based model, objects are instances of classes. In a classless model, like Cecil's, there are only objects, and they can have their own individual behavior.

The ideal back-end app developer

What you’re looking to see on the Cecil (programming language) engineer at this point.

At this point, a skilled Cecil (programming language) engineer should demonstrate strong problem-solving abilities, proficiency in Cecil (programming language) 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 Cecil (programming language).

What does this simple code snippet do in Cecil?
def addNumbers(a, b) -> result
  result := a + b
This code defines a function called 'addNumbers' which takes two parameters, 'a' and 'b'. The function adds the two parameters and assigns the result to the variable 'result'.
What will be the output of this Cecil code snippet?
def main()
  def x := 5
  def y := 10
  print(x + y)
This code will output the number '15'. It defines a function 'main' which declares two variables 'x' and 'y' with values '5' and '10' respectively. It then prints the sum of 'x' and 'y'.
What does this Cecil code snippet do?
def processArray(arr)
  for i in arr do
    print(i * 2)
This code defines a function 'processArray' that takes an array 'arr' as a parameter. It then iterates over each element in the array, multiplies it by 2, and prints the result.
What does this threading related Cecil code snippet do?
def threadExample()
  def t := Thread new: {print('Hello World')}
  t start
This code defines a function 'threadExample' which creates a new thread 't'. The thread 't' prints 'Hello World' when started. The 'start' method is used to start the execution of the thread.

Wrap-up questions

Final candidate for Cecil (programming language) 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 Cecil (programming language) application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

How would you implement polymorphism in Cecil?
Polymorphism in Cecil can be achieved through multiple dispatch, which allows a method to be selected based on the runtime types of all its arguments.
What is the role of the static scope rule in Cecil?
The static scope rule in Cecil determines how names are resolved. It allows a name to refer to the nearest enclosing definition of that name.
How would you optimize a Cecil program for performance?
Optimizing a Cecil program for performance could involve techniques such as avoiding unnecessary object creation, using efficient data structures, and minimizing I/O operations.
