the test conducted in 2013 had two papers:
1. english essay
2. english general

the written test was conducted in march and only 6 candidates passed out of 499, for one seat.

but since then, things have changed and as mentioned in the advertisement, screening will take place followed by an interview call
Given the SPSC formula, 4 candidates per seat will be called for interview, since there are 4 seats in total.
