INFOSYS PAPER & INTERVIEW - 09 OCT 2005 - MUMBAI

Posted By : Aashwin Rating : +6, -0

Dear Friends
I am passing on Infosys paper test held on 9th  Oct 2005 at Sydneham College, MUMBAI. And the subsequent interview experience.

FIRST OF ALL THANKS TO Friends MAM FOR THIS WONDERFUL GROUP. It truly helped me for preparation.
 
Some tips for preparation:
 
I did Shakuntala Devi Puzzle to Puzzle and More puzzle. In one of the Friends mails only I had found explanations for few Shakuntala Devi Puzzles..it really helps, u get idea how to proceed any problem.
 
Then previous Papers are must. Qnes r repeated they save your time and that u can devote  to new puzzles in paper during test. This will boost ur confidence while solving. My test had nearly 50% puzzles repeated. So previous papers really helped me a lot. Acc to me PREV PAPERS IS THE KEY TO CRACK THE TEST.
 
George Summers rough overview is good if times there go a bit thoroughly but don't spend much time
 
NOW THE PAPER:
 
10 Puzzles   1 hr

Then they asked in detail each one regarding robotics  ..i explained all mechanism Then paper pres what topics seminars which all in grp or alone .they asked in grp how was it working? any probs u faced? how u solved. I told ya every person has his/her own ideas /views we discussed it out sometimes fought but overcame it and came out with what is best for as a team. they were impressed.
 
As the robotics car topic was going on the senior lady asked me how I will design a car for 1 legged and 1 hand person. This was a bit tough to impress her then also I handled it by giving her maximum ideas as I could all thru she was asking how I will design the steering ,the brakes clutch etc the gear systems first I felt little tough but then I thought i am not gonna loose it maintained my confidence.
