It is a functional, dynamically typed language for building scalable and maintainable programs on top of Erlang’s VM and compiling Erlang bytecode.

When José Valim invented it in 2011, the Erlang VM ecosystem obtained a language that focuses on concurrency, reliability, and scalability. The fact that it scales effectively without compromising speed makes it an excellent choice for apps or websites that will serve millions of people simultaneously.

Elixir features that will make it relevant in 2022

Scalability: All Elixir code is executed inside lightweight, isolated processes that interact through messages.

Concurrency: Elixir may run numerous processes concurrently, all of which are controlled in real-time and do not have any negative implications or slow down the application.

Fault Tolerance: Elixir allows managers to describe how to restart pieces of your system by incorporating built-in safety protocols that enable the product to run even when anything goes wrong.

Functional programming is a coding style that encourages developers to write concise, quick, and simple code to maintain.

Erlang Compatibility: Elixir runs on the Erlang Virtual Machine, providing developers full access to the Erlang environment.

Elixir has a suite of development tools. Setting up projects, assigning responsibilities, and running tests have never been easier than they are with Mix. Hex, the package manager, is included as well.

Elixir Language Applications

Consider switching to a different programming language if a single activity requires many CPU resources, such as a complex mathematical issue.

However, Elixir is likely to be a good match for any use case that is neither CPU-bound nor essentially sequential. If your system has a lot of connections that are I/O bound, Elixir may be a good fit for you. Web servers, APIs, online apps, and chat backends (such as Facebook Messenger and WhatsApp) are current use cases in which this assertion holds.

The Use of Elixir in Live Production

Elixir is used in various ways by firms across a wide range of sectors to start new ventures and expand existing ones. Discord, Heroku, Adobe, Motorola Solutions, and many other firms are among them.

Hiring an Elixir Developer for your team

It’s important to go beyond the most popular programming languages like Java, C++, PHP, and JavaScript, since they may include functionality that isn’t available in more widely used languages. While elixir developers are few, it’s important to remember that there aren’t many prospects for development or learning for the developers themselves.

A look at the features and applications of Elixir programming has been discussed.

If you’re looking for the greatest Elixir software developer, you’ve come to the correct spot!

Candidates’ technical knowledge and comprehension may be tested using the following question types.


A key, which is the best response to the question, and a few distractors, which are persuasive but erroneous answers, are all aspects of a multiple-choice question (MCQ), which is a kind of essay question.

The following are some coding questions.

A wide variety of questions are available to assess a candidate’s abilities in various ways. The coding abilities of the applicant might be tested during a screening process for a developer position.

Questions to Ask a Potential Elixir Developer

  • What is the purpose of the Crypto module in Elixir?
  • Mention the spawn function?
  • Define string interpolation in Elixir.
