IT companies are progressively shifting from traditional methods to automated assessments for analysing a job applicant’s technical skills. The challenge with traditional methods is that they are time-consuming and provide less accurate results. Resume perusals and telephonic conversations are not suitable for assessing the technical knowledge and capabilities of candidates. You can efficiently evaluate technical skills only with domain-based online tests that are relevant, measurable, customisable, and also provide the desired results.

When it comes to hiring professionals with knowledge and expertise in OOPS, MeritTrac’s domain-based tests can come in handy. You can use these tests to hire software engineers, application developers, software developers, and other related profiles. The tests enable detailed knowledge of a wide range of OOPS programming concepts. You can narrow down your search by customising the pre-designed OOPS interview questions based on the job you are hiring for.

Applications of MeritTrac Assessment Solutions

Automated domain assessment tests have proven to be effective in recruiting skilled candidates. The auto evaluation feature of these assessments highlights the candidate’s technical skills and expertise. This reduces the hiring time, cost, and effort. It also removes any chance of bias or personal preferences during candidate selection. This has resulted in improved productivity and performance of the organisation’s software teams. When the chosen candidates have all the required skill sets for working on a project, they can grow in their respective roles. This will subsequently lead to lower attrition rates. 

MeritTrac’s online tests featuring OOPS interview questions are often used in first-level screening during mass recruitment processes. The online test format allows you to administer the test to hundreds of candidates at the same time. In just a few hours, you can filter out candidates with knowledge of OOPS concepts and invite them for an interview. MeritTrac’s intelligent coding assessment platforms feature project-based tests to evaluate coding skills. This will significantly cut down your hiring time.

You can also create training and development programs for existing employees by administering the OOPS test periodically. The analytics derived through these tests provides insights on employee competencies and help to bridge any skills gaps.
