I also feel sorry for you. For me this is not the only one in the past four and half years, always cleared written but never went through the interviews -- not because of having any difficulties but due to something else.

This time it's a different story.

So, the conclusion is that:

(1) Minimum qualifications + age required
(2) written
(3) psychological test
(4) interview

There was no use of academic marks/percentages into the final calculations for making the list of candidates, except for the entry level. Therefore the written merit was held high in ranking and the psychological test was again used as only for fit or unfit purposes, I believe.
