Inside This C# Online Assessment

The C# Online Test evaluates candidates’ knowledge of C# Programming, basics of MS SQL, expertise in WCF basics and architecture, knowledge of bindings and contracts in WCF, MS SQL database query writing skills and hands-on programming skills in C#. The 60-minute online assessment contains 15 MCQs and two coding problems that objectively and effectively evaluate the candidate's domain knowledge and programming skills.

The C# Online Test also gauges the hands-on programming skills of an applicant through a simulator-based coding problem. The test is thoughtfully crafted and validated by Mercer | Mettl's team of experts, ensuring that the assessment is comprehensive and the questions are framed per current industry standards. The assessment reports offer detailed insight into the applicant's strengths and development areas, enabling evaluators to make the best hiring decision.

Key profiles this C# Online Test is helpful for: 

  • C # WCF SQL server developer 
  • WCF developer 
  • C # SQL developer 


C# has become one of the most popular languages and has received great acceptance among professional programmers and developers. With a thriving open-source ecosystem that enables developers to build custom software, websites, mobile apps, etc., C# has been a go-to language for most developers. The inherent simplicity of C# lends unparalleled ease to developing useful and functional applications for programmers and development teams.

Its unprecedented popularity is one of the reasons why the demand for C# developers is growing at a meteoric pace. However, identifying accomplished developers is a colossal task for recruiters and hiring managers. A data-led screening approach helps recruiters understand potential applicants' domain knowledge, skills and competencies. This approach is far more objective and efficient than assessing someone's suitability through resumes, past achievements, or academic credentials.

The C# Online Test is a pre-hire assessment to gain holistic insights into candidates' potential and competency, including their strengths and areas of improvement, to assess their suitability for developer positions. The test is a surefire way to gain an idea of a candidate's job fit through an in-depth evaluation that uncovers whether a person is a right fit and capable of delivering outstanding results.

Identifying the crème de la crème can seem a bit far-fetched with an evaluation process that does not include technical skills assessment. However, using the C# Test can enable the recruiting experts to undertake an objective and comprehensive technical evaluation for identifying which candidates are the perfect match for the job requirements.
