Psychological test had three sections. The first one was an English based test to judge applicant's character and behavior. It had questions like that:
1. Do you think you are lucky?
Options : strongly agree, agree, neutral,disagree, strongly disagree.
2. When I'm in anger, I shout and break things.
Options : strongly agree, agree, neutral,disagree, strongly disagree.

And others.

The second questionnaire had similar types of questions in Urdu with options in Urdu.

In the third section, you had to draw pictures of a soldier, a house etc. and there was also a story section in which you have to write a story on the given picture within five minutes.

The interview is normally scheduled the very next day and the interviewing lady asked me to tell about myself and then about Pakisan. She asked me if I had anger issues? I replied that even the nicest person has his limits, Isllye Kabhi Kabhi ajaya he Gussa. She then asked me that how do I control my anger once I get angry and blah blah.

Just try to be positive and be yourself. Everything will be okay. These interviews are just a formality. And almost every person clears this test.
