Ask the right questions to secure the right Alice talent among an increasingly shrinking pool of talent.
Alice is a 3D educational programming language developed by Carnegie Mellon University. It was first released in 1994 and is based on the Logo programming language. Alice is designed to teach introductory computer science concepts to students in a visual and interactive way. The language has been used in classrooms around the world and has been cited as a successful tool for teaching computer science.
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.
The setup method in Alice is used to initialize the program. It's the first method that's called when the program runs.
In Alice, a new method can be created by selecting the 'create new method' option in the methods tab of the details area. You can then name the method and define its behavior.
Methods perform an action on an object, while functions return a value. In Alice, every method is a procedure and every function is a question.
The key elements of Alice programming are objects, methods, events, and control structures.
Object-oriented programming in Alice is a method of programming where we model real-world things using classes and objects. It allows for encapsulation, inheritance, and polymorphism.
Past experience can show that the candidate can apply their skills in a practical setting and handle the demands of the job.
The tech field is always evolving, so a successful candidate should show a willingness to keep their skills up to date.
Creativity is key in development to find innovative solutions and think outside of the box.
Clear communication is important because developers often work in teams and need to explain their work to non-technical stakeholders.
Problem-solving skills are crucial because coding often involves troubleshooting and finding solutions to complex problems.
This is essential because a deep understanding of Alice programming is fundamental to the position.
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.
In Alice, a local variable is only accessible within the method where it's declared, while a global variable can be accessed by any method in the program.
Variables in Alice can be used to store and manipulate data. They can be created by selecting the 'create new variable' option in the properties tab of the details area.
In Alice, a single-line comment is a note for a specific line of code, while a multi-line comment can span several lines. They're used to explain the code and are ignored by the compiler.
In Alice, the control structures are sequence, selection, and repetition. Sequence is the default control structure, selection includes if/else statements, and repetition includes loops.
To create a new event in Alice, you would go to the events tab and then click on 'create new event'. You can then define the event and its behavior.
A skilled Alice engineer should demonstrate strong problem-solving abilities, proficiency in Alice 3D programming, and effective communication skills. Red flags include lack of knowledge about the software's features, inability to explain complex concepts simply, or a poor track record of teamwork.

Alice does not natively support exception handling. However, we can use conditional statements to check for potential problems and handle them accordingly.
In Alice, the 'While' loop repeats a block of code while a condition is true, while the 'For all in order' loop repeats a block of code for each item in a list.
The 'While' loop in Alice is used to repeat a block of code while a certain condition is true. You can use it by dragging and dropping it into the method editor, defining the condition, and then adding the instructions.
The 'Do together' control structure in Alice is used to execute multiple instructions at the same time. It's useful for creating parallel actions.
The 'Do in order' control structure in Alice is used to execute a series of instructions in the order they appear. You can use it by dragging and dropping it into the method editor and then adding the instructions.
