What is Interview?

Frankly speaking interview is nothing. you can take it as conversation between some people.
Let's say you are talking to your friends or introducing yourself for the first time this is what interview is, this corporate conversation is called as interview.

Interview = Conversation + Formal

What does company want from you they only need that you are one who is trustworthy . They take test in such a way that they forcefully, indirectly irritate you.
such as you will be called for an interview at 8:00 a.m. and your will start at 6:00 p.m. they just want to check your patience level.

I personally believe that you are the one who will introduce yourself in better way rather than what your resume says. Resume is something so called paper that say 'who you are ? ' 
In today's world i believe that yes competition has increased. you only have to show that how different you are from rest world.

MANTRA : 

if you lie yo your interviewer, lie in such a way that he forced to believed you that you are not wrong.
