Inside this Erlang Test

The Erlang Online Assessment enables recruiters and employers to comprehensively assess the applicant's skills in the Erlang language. This test, developed and validated by subject matter experts (SMEs), helps reduce the hiring time significantly and identifies the job-fit candidates - as per industry standards.

Erlang is a functional, general-purpose, concurrent programming language and a garbage-collected runtime environment. It was designed to build distributed, fault-tolerant, concurrent systems. It has been extensively used in various large telecommunication systems from Ericsson and has been preferred by several global firms, including T-Mobile and Nortel. That is why organizations look for experienced and junior developers proficient in Erlang.

The Erlang Online Assessment is the most effective screening method for prospective employers to validate a candidate's technical, on-the-job skills before an interview. The technical test helps filter out unwanted candidates, allowing recruiters to focus time and energy on interviewing only suitable candidates. Most importantly, the test result reports are objective and insightful and provide a granular understanding of the candidate's skills and abilities most critical for success in the role. The test includes 30 carefully selected multiple-choice questions (MCQs) to be completed in 45 minutes. 

The test helps screen candidates for the following roles:  

  • Erlang developer 
  • Backend developer - Erlang 
  • Software developer - Erlang 


Originally invented in 1986 by Ericsson as a proprietary language, Erlang language was the brainchild of a trio comprising Mike Williams, Joe Armstrong and Robert Virding. Erlang is extensively used across various industries, including Blockchain, IoT, Fintech, banking, e-commerce, etc., making it invaluable in their production systems. Initially, Erlang was built to enhance the telephony applications development process. Since then, it has grown and become essential for Erlang software engineers to develop soft real-time applications that are massively scalable and user-friendly. Moreover, there are a plethora of other features that attest to its popularity among developers. Even though it is not a complicated language to master, Erlang developers must demonstrate a high-level competence and capabilities that make them indispensable at work.

There are numerous ways to source tech talent for organizations seeking skilled Erlang developers, from online job postings to outsourcing companies' services. But how would employers know if the candidates they select are well-prepared for the projects to be taken up? Hiring unskilled Erlang programmers may translate to project delays, leading to cost overruns and stakeholder disappointment. Hence, one should hire only those candidates that tick all the boxes when it comes to competency and experience.

An effective way to ensure developer candidates have the right experience and knowledge in line with the employer's expectations is to include Erlang Online Pre-employment Test in the hiring process. Giving them a technical assessment to see if their skills match the job description requirements enables recruiters and hiring managers to confirm if the candidate is the right choice for the role. In addition, the Erlang Language Test is time sensitive to determine whether applicants can work under strict deadlines. Therefore, when applicants undergo such a skills evaluation process, employers can be sure that the candidates are carefully vetted and screened before the interview.

Erlang Pre-employment Assessment allows employers to zero in on candidates most suitable for a given job. This test includes multiple-choice questions (MCQs) to objectively evaluate test-takers concerning their technical skills, knowledge, and abilities. Moreover, the test result reports are comprehensive and insightful to help employers ascertain if developers are well-versed in Erlang.
