Hey Friends

I attended infy exam om 6th august in hyderabad.About 5-6 qusetions were repeated but i did know that. I am happy as i qualified the exam and finished my interview yesterday in Infosys campus. One thing what i would like to mention, approach is very important, i attempted 9 questions in which one was surely wrong...but it was for the first time I solved most of the  my approach was in my own try to solve th sum in ur own way,..there will be "n" number of ways to solve the sum....I am saying this because people who said that they solved 9 questions corectly..did not get through...

Be careful with English..take time and answer it...dont try to solve puzzles in that time...It may appear easy but it has traps.. I am just crossing my fingers and waiting for the result of interview.

My interview was in 10:40 slot...but i was called at about guys remember if u r attending off campus then they will make u wait...

The pannel consisted two men who wre above 45. I had stress kind of interview.

I was asked to keep my certificates and resume...aside.
I was not asked to introduce myself (thats the only chance u get speak abt ur accomplishements)

One person was asking questions and the other was careful....u have to make an eye contact with both of them.

He asked about my fathers occupation...then asked to speak abt my final year project.

I had done an internship in TCS and I started speaking abt that.... I just mentioned few points and i was abt to get into a flow ...he stopped me and asked y did TCS did not absorb u...I replied its the policy of TCS that they do not recruit interns....

Then he asked y I did not join my college was center for JKC recruitment (It was difficlt for me to convince them)..

Then he asked to chose a topic and talk on that....I chose "MY CAMPUS LIFE".. I chose this because i thought i wud get a chance to speak abt my self... but then again he stopped in middle and asked me to speak only abt CAMPUS LIFE and not abt myself.

Then he gave me a puzzle....I was asked to fill a square with no.s ranging from 1-9...such tat the total should be same...He asked me where wud i start from..i said middle square....and then we had few arguements there.

Then he asked me to ask him a question...

I asked him ...y Infosys is not in product devlopment.....



I SAID...I AM sorry...

Then i asked where wud be my posting....he said that wud depend on business requirements.... he asked if u have any location constraint ..he would write it there...

I said i dont have any preference. he repeated it twice...

So guys appear honest.....

If u have any queries contact me at
