Adaface IBM Mainframe Online Test is the most accurate way to shortlist Mainframe Developers

Reason #1

Tests for on-the-job skills

The Mainframe Online Test helps recruiters and hiring managers to identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates.

The Adaface Mainframe Online test screens candidates for the typical skills recruiters look for Mainframe Developer roles:

  • Strong knowledge of COBOL (CICS), CA7, DB2 and/ or SQL, Other Mainframe Technologies & Tools
  • Experience Developing, troubleshooting, and modifying Mainframe systems
  • Understanding of the complex logic of COBOL and PL/I applications
  • Ability to quickly identify code errors
  • Vast knowledge of business processes in specific industries

The insights generated from this assessment can be used by recruiters and hiring managers to identify the best candidates for the Mainframe Developer role. Anti-cheating features enable you to be comfortable with conducting assessments online. The Mainframe Developer test is ideal for helping recruiters identify which candidates have the skills to do well on the job.

Reason #2

No trick questions

no trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Why we started Adaface ->
Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment IBM Mainframe Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the IBM Mainframe Test from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.
