Many Recruiters use group discussion (GD) to test a candidate's communication skills, leadership skills, test topic knowledge, etc. There are also two other types of GD that test the lateral thinking of a candidate.
Aptitude tests are a great way for a hiring manager to gauge a candidate’s suitability to a role. They are a tool used to see how candidates might deal with the challenges of the role they are interviewing for.
