Product Perfect

Ceptre is a rule-based programming language designed for interactive storytelling and game design. It was developed by Chris Martens at the University of California, Santa Cruz in 2015. Ceptre facilitates the creation of complex narratives through declarative logic programming, enabling the simulation of intricate systems. Its unique approach allows for procedural content generation, making it particularly useful in game development and interactive media. The language's source code is publicly available on GitHub, promoting open-source collaboration and innovation.

First 20 minutes

General Ceptre (programming language) app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Ceptre (programming language) 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 Ceptre?

The basic data types in Ceptre are atoms, variables, and predicates.

How would you declare a predicate in Ceptre?

In Ceptre, a predicate is declared using the following syntax: 'predicate_name(parameters).'

What is a rule in Ceptre and how is it used?

A rule in Ceptre is a logical construct that allows the developer to define certain behaviors or actions. It consists of a rule head and a rule body.

What is the purpose of a linear logic in Ceptre?

The purpose of linear logic in Ceptre is to allow the developer to manage resources and express constraints in a program.

Describe the difference between atoms and variables in Ceptre.

Atoms in Ceptre are constant values, while variables are placeholders that can hold different values.

Next 20 minutes

Specific Ceptre (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.

How would you use the 'add' operator in Ceptre?

The 'add' operator in Ceptre is used to add two or more numbers. For example, 'add(2, 3)' would return 5.

What are the control structures available in Ceptre?

Ceptre provides a variety of control structures such as conditional statements, loops, and function calls.

How would you define a function in Ceptre?

A function in Ceptre is defined using the 'def' keyword, followed by the function name, parameters, and body.

What is the purpose of the 'cut' operator in Ceptre?

The 'cut' operator in Ceptre is used to control the backtracking of a program.

Describe the difference between 'cut' and 'fail' operators in Ceptre.

The 'cut' operator in Ceptre is used to stop backtracking, while the 'fail' operator is used to force backtracking.

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

What does the following Ceptre code do?
state world = { alive }.
rule die = { alive } --> { dead }.
This code defines a state 'world' with an initial state 'alive'. The rule 'die' then changes the state from 'alive' to 'dead'.
What will be the output of the following Ceptre code?
state world = { alive }.
rule die = { alive } --> { dead }.
query world.
The output will be 'dead'. The initial state of the world is 'alive', but the rule 'die' changes it to 'dead'. The query then returns the current state of the world.
What does the following Ceptre code do?
state list = { a, b, c }.
rule remove = { X } --> { } when member(X, list).
query list.
This code defines a state 'list' with elements 'a', 'b', and 'c'. The rule 'remove' removes an element 'X' from the list if 'X' is a member of the list. The query then returns the current state of the list.
What does the following Ceptre code do?
state world = { alive }.
rule die = { alive } --> { dead }.
query world.
rule revive = { dead } --> { alive }.
query world.
This code defines a state 'world' with an initial state 'alive'. The rule 'die' changes the state from 'alive' to 'dead'. The first query then returns the current state of the world. The rule 'revive' then changes the state from 'dead' back to 'alive'. The second query then returns the updated state of the world.

Wrap-up questions

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

How would you implement recursion in Ceptre?

Recursion in Ceptre can be implemented by calling a function within itself.

What is the role of the 'is' operator in Ceptre?

The 'is' operator in Ceptre is used to evaluate mathematical expressions.

How would you handle exceptions in Ceptre?

Exceptions in Ceptre can be handled using the 'catch' and 'throw' constructs.
