“Personality is to a man what perfume is to a flower.”
According to me, personality is something which you acquire throughout your life journey and can’t be changed in a month or two. Many make a mistake to wait till the declaration of CSE Mains result to begin their preparation for this last stage. This costs them a year. I have seen the personality test from very closed.
I myself have attended 4 CSE Personality tests, which gave the real insight about what is UPSC looking for. I have scored both high (195) and low (151) in the personality test, so I know what mistakes generally candidates commit. I am also one of them.
