First 20 minutes

General Ioke app knowledge and experience

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

How would you define Ioke?

Ioke is a dynamic, strongly typed, prototype-based programming language. It is designed to be expressive and flexible, with a focus on metaprogramming.

What are the key features of Ioke?

Ioke has several key features, including dynamic typing, prototype-based object orientation, and a powerful macro system. It also supports first-class functions, lexical closures, and arbitrary precision arithmetic.

Describe the difference between Ioke and other dynamic languages like Ruby or Python.

Ioke is more flexible and expressive than many other dynamic languages. It has a more powerful macro system and supports more advanced metaprogramming techniques. It also has a unique prototype-based object system, unlike the class-based systems used in Ruby and Python.

How would you create a new object in Ioke?

In Ioke, you can create a new object by cloning an existing one. For example, you could create a new object based on the default Object prototype with the code 'obj = Object clone'.

What are the main data types in Ioke?

Ioke has several main data types, including Numbers, Text, Lists, Dicts, and Cells. It also has a unique Nil type, which represents the absence of a value.

Next 20 minutes

Specific Ioke 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 a Cell and a Message in Ioke.

In Ioke, a Cell is a storage location for a value, while a Message is a piece of code that can be sent to an object. Cells are similar to variables in other languages, while Messages are similar to method calls.

How would you define a method in Ioke?

In Ioke, you can define a method by assigning a Message to a Cell. For example, you could define a method that adds two numbers with the code 'add = method(x, y, x + y)'.

What are the control structures available in Ioke?

Ioke has several control structures, including conditionals (if, unless), loops (while, for), and exception handling (rescue, ensure). It also supports pattern matching and destructuring.

Describe the difference between lexical and dynamic scope in Ioke.

In Ioke, lexical scope means that a variable is accessible within the block where it is defined and any nested blocks. Dynamic scope, on the other hand, means that a variable is accessible within the method where it is defined and any methods called from that method.

How would you handle exceptions in Ioke?

In Ioke, you can handle exceptions using the 'rescue' control structure. You can also use 'ensure' to guarantee that certain code is executed whether an exception is raised or not.

Oops! Something went wrong while submitting the form.

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

What does the following Ioke code do?
message("Hello, World!")
This code prints the string 'Hello, World!' to the console.
What will be the output of the following Ioke code?
x = 10; y = 20; x + y
The output will be 30. The code assigns 10 to x and 20 to y, then adds x and y.
What does the following Ioke code do?
list = [1, 2, 3, 4, 5]; list select(x, x > 3)
This code creates an array with the elements 1 to 5, then selects and returns a new array with the elements that are greater than 3, which are 4 and 5.
What does the following Ioke code do?
future = concurrent future({ 2 + 2 }); future get
This code creates a new future that computes the sum of 2 and 2 in a separate thread. The 'get' method is then used to retrieve the result of the computation, which is 4.

Wrap-up questions

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

What are the concurrency features in Ioke?

Ioke has several concurrency features, including futures, promises, and actors. It also supports software transactional memory for safe, concurrent access to shared data.

Describe the difference between a future and a promise in Ioke.

In Ioke, a future is a value that is being computed in a separate thread and will be available at some point in the future. A promise, on the other hand, is a placeholder for a value that will be provided later, possibly by another thread.

How would you write a macro in Ioke?

In Ioke, you can write a macro by defining a method that takes a Message as an argument and returns a new Message. The macro is then invoked by sending the Message to an object.
