This is not the first time SpiceJet is using a COMPASS test and Complex Control Task
This was introduced back in 2014 when they conducted an exam for 737 Type rated FO's
It was used again earlier this year for an internal exam
So this Q400 vacancy would be the 3rd time they are using this test . The only difference was earlier the COMPASS test was Phase 1 and CPL subjects was Phase 2
And there is no final interview . You pass the final phase 4 (i.e psychometric test ) you get the job
