Ask the right questions to secure the right Fantom talent among an increasingly shrinking pool of talent.
Fantom is a general-purpose, object-oriented programming language that was initially released in 2005 by Brian and Andy Frank. It was designed to be portable across various platforms including Java Virtual Machine (JVM) and JavaScript interpreters. The Fantom ecosystem includes a standard library, a build system, testing framework, and documentation toolset. Its syntax is similar to C#, Java or Kotlin with added features for concurrency management inspired from Erlang's actor model. Despite its versatility and robustness as an efficient cross-platform development tool, it remains relatively obscure within the broader software development community.
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 Fantom, exceptions are handled using 'try-catch' blocks. You can also use the 'throw' statement to throw an exception.
The 'using' statement in Fantom is used to import a namespace or a type into the current scope. It is similar to the 'import' statement in Java.
In Fantom, you would create a class using the 'class' keyword followed by the class name. For example, 'class MyClass { }'.
Fantom has several key features including: static and dynamic typing, functional programming, concurrency programming, and a standard library that includes a cross-platform API for file I/O, serialization, reflection, and more.
Fantom is a general-purpose, object-oriented, portable programming language that runs on the Java Runtime Environment (JRE), JavaScript, and .NET Common Language Runtime (CLR). It is designed to be easy to use, with a familiar syntax for Java and C# developers.
The tech field is always evolving, so it's important for developers to be able to pick up new technologies quickly.
Past experience can be a good indicator of how well the candidate will perform in the role.
Good communication skills are important for working in a team and explaining technical concepts to non-technical team members.
Knowing how to use the right tools can greatly increase efficiency and effectiveness in development.
This is important because coding and development often involve solving complex problems and finding solutions.
This is crucial as the candidate needs to have a good grasp of the language to be able to develop effectively.
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 Fantom, you can create a singleton using the 'singleton' keyword. For example, 'singleton class MySingleton { }'.
The 'sys' pod in Fantom provides core functionality and types that are used by all other pods. It includes basic types like Int, Str, Bool, and more.
In Fantom, static typing means that the type of a variable is known at compile time, while dynamic typing means that the type of a variable is known at runtime. Fantom supports both static and dynamic typing.
In Fantom, concurrency is implemented using the 'Actor' model. You can create an actor by extending the 'Actor' class and overriding the 'receive' method.
Mixins in Fantom are a type of inheritance that allows you to include behavior from multiple sources in a class. They are similar to interfaces in Java, but they can also include implementation code.
A skilled Fantom engineer should demonstrate expertise in Fantom language and related technologies, strong problem-solving skills, and experience with systems integration. Red flags include lack of specific examples in their work history or inability to articulate complex technical concepts clearly.
class Hello {
static Void main() {
echo("Hello, World!")
}
}class Test {
Int add(Int a, Int b) {
return a + b
}
}class Main {
static Void main() {
list := [1, 2, 3, 4, 5]
list.each |Int num| { echo(num * 2) }
}
}class Main {
static Void main() {
ActorPool().startup
Actor { echo("Hello, World!") }.send
}
}class Person {
Str name
Int age
new make(Str name, Int age) {
this.name = name
this.age = age
}
}class Main {
static Void main() {
echo(Str.locale("en", "US").decimal(1234567.89))
}
}The final few interview questions for a Fantom candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.
Performance in a Fantom application can be optimized in several ways, including: using efficient algorithms and data structures, minimizing I/O operations, using concurrency to parallelize tasks, and profiling the application to identify bottlenecks.
The 'it' keyword in Fantom is used in closures to refer to the single argument passed to the closure. It is similar to the 'this' keyword in Java, but for closures.
In Fantom, polymorphism is implemented through inheritance and interfaces. A class can inherit from another class or implement an interface, and then override the methods defined in the superclass or interface.
In Fantom, 'const' is used to declare a constant, whose value cannot be changed once it is assigned. 'val', on the other hand, is used to declare a read-only field, whose value can be assigned once, but cannot be changed afterwards.
Closures in Fantom are anonymous functions that can capture variables from their surrounding scope. You can use them as arguments to higher-order functions, or to create function-like objects.
