HOW DIFFICULT IS IT TO PASS

                         SELECTION TESTS?

The problem for the candidate is this: 
there is no 'pass-mark' for any of the tests.

Typically a firm will test 3000 candidates out of which they will select only 100 for interviews for training.  If you say that these 100 have 'passed' then 2900 have 'failed'.  Naturally the firm will choose the people who have performed the best in order to interview them before final selection.

THE PLAIN FACT OF THE MATTER IS THIS:

Firms use TESTS to eliminate most of the candidates who apply for training positions.  In this sense it is very difficult to 'pass' this TEST BARRIER.
