“As a Talent Acquisition Manager, I observed that my team spent too much time in interviewing irrelevant candidates. So our team created an Aptitude evaluation test called Uneecops Common Aptitude Test (UCAT) with the help of iMocha. Now, we share the test with the candidates & based on the assessment report we were able to filter 170 good candidates from the pool of 300.”
