Erlang Coding Tests

When looking for your next Erlang expert, ensure they can build scalable, fault-tolerant systems and use Erlang’s unique strengths in distributed computing.

TestGorilla’s 12 universal coding tests assess vital programming skills across 20 languages, including Erlang. Ultimately, they help you identify developers with the right mix of coding expertise, problem-solving capabilities, and strategic thinking for your team.

Erlang coding test

What is an Erlang skills test?

Erlang is a general-purpose programming language first released by Ericsson in 1986. It’s used to build scalable systems with high availability requirements and fault tolerance. Erlang and the Open Telecom Platform (OTP) libraries are popular in industries such as e-commerce, telecom, and banking.

Hiring Erlang developers by relying solely on resumes, portfolios, and interviews leaves you vulnerable to mis-hires. Instead, you need to test candidates' programming abilities in a controlled environment. The most elegant way to do this is with an Erlang skills test – a set of online coding challenges that assess your candidates' language proficiency.

TestGorilla's Erlang assessment evaluates essential programming know-how, like debugging and performance optimization, alongside Erlang-specific skills, such as implementing fault-tolerant systems and using hot code load.

Why use Erlang skills tests?

  • Test real-world skills: TestGorilla's coding tests are prepared and regularly updated by experienced programmers, evaluating skills relevant to modern workplaces.

  • Rank your top candidates: Get an auto-scored ranking of developer candidates and save hours by not building and scoring homemade coding tests.

  • Test different technical skills: Combine Erlang coding tests with other technical tests that check candidates' role-specific skills in areas such as finance and data analysis.

  • Go beyond the outputs: Coding test results give you a timeline so you can check candidates' thinking processes and test cases. Combine these insights with soft skills tests to assess abilities such as communication and leadership for a holistic evaluation.

  • Find long-term team members: A strong skills and culture fit means top developers stay for longer 91% of tech companies saw skills assessments boost staff retention.

What roles can you hire for with an Erlang coding test?

Erlang software engineer

Erlang software engineers develop systems prioritizing scalability, concurrency, and fault tolerance. For instance, they may work on real-time systems such as instant messaging apps or payment gateways. Some roles prefer knowledge of CI/CD, IT systems, and network infrastructure. Erlang software engineers may be required to know or learn additional languages such as C, Java, or Go.

Erlang back-end engineer

Erlang back-end engineers design, build, and maintain distributed server-side systems, often in industries like telecoms and finance. They tune low-latency, high-performance platforms using Erlang systems programming and OTP libraries. Docker and Kubernetes experience may come into play in this role.

Erlang full-stack engineer

Erlang full-stack engineers build scalable, fault-tolerant back-ends using Erlang and integrate them with user-facing interfaces. They design and manage APIs and optimize the server side for concurrency and performance. They must also have deep knowledge of databases (e.g., Mnesia and front-end frameworks (e.g., Nitrogen).

Erlang principal engineer

Erlang principal engineers are senior technical staff who design and oversee complex systems built with Erlang. For instance, they may lead projects in low-latency telemetry systems. On top of a thorough understanding of Erlang's "let it crash" philosophy and OTP libraries, principal engineers expertly apply DevOps and agile/scrum methodology practices.
