The second part of the interview contains Group Testing Officer's (GTO's) Test. While the first part aims at testing the intelligence and frame of mind of a candidate, the GTO's test is a complete test of one's personality, including physical fitness, mental alertness, leadership qualities, planning flexibility, expression, knowledge, argumentative capabilities, etc. In other words, the performance of every candidate is gauged as a member of a group, and leader of the group, so that his/her behaviour as equal, superior or subordinate is keenly observed and assessed. The group worthiness of a candidate is tested. 

The GTO's test includes the following nine broad sub-tests: 

Group discussion 
Group planning exercise 
Group obstacles 

PGT

FINAL GT
Command Task
