Elixir Coding Tests

When you hire Elixir developers, look for proficiency in Elixir, Erlang's OTP libraries, and frameworks such as Phoenix. They should be comfortable building concurrent, fault-tolerant distributed systems. You must also check that they excel at writing clean code, debugging, and other role-relevant skills, such as team leadership and project management.

A universal coding test spotlights crucial programming skills, including performance optimization, debugging, and algorithmic problem-solving. Also, developers code in the languages they're most confident in, giving you more accurate candidate rankings. While syntax matters too, in practice, developers often pick up new languages on the job.

Creating an Elixir assessment on TestGorilla can take just a few minutes. You select up to five scientifically validated tests based on your role requirements. For example, combine the Entry-Level Algorithms test and the REST APIs test and add cognitive, situational, or role-based tests (e.g., project management) for a holistic assessment.

Create a custom coding test for Elixir candidates by first deciding what real-world business problem you'd like candidates to solve (e.g., building an instant messaging system). Then, write the test instructions and provide the coding challenge's inputs and outputs. Also, add test cases that help calculate test scores and allow candidates to test parts of their code.

Ideally, your Elixir hire should have previous experience, especially for strategic roles requiring in-depth knowledge of its tools and libraries. However, it's not a must every time. For example, developers who program in Erlang or other functional programming languages can adapt quickly to Elixir. Instead of making Elixir compulsory, you could test candidates' knowledge of concurrency, distributed systems, and other Elixir characteristics.

When interpreting Elixir coding test results, check the overall test score and individual test cases' correctness scores. These tell you if a candidate wrote an effective algorithm. In addition, view the test timeline and individual test cases and assess language-agnostic coding skills such as readability and Elixir-specific ones such as using OTP libraries.
