    Hi friends, my name is ARUP KUMAR SINGHA ROY.

    I have done B.tech in ELECTRONICS AND INSTRUMENTATION ENGG from TECHNO INDIA(SALT_LAKE) in the year of 2009,  i cleared the aptitude, and as well as crack the interview also, i got the confirmation mail on my B'day(3rd SEP), that is the best B'day gift.
    Now gonna share some Experiences.

    CS-IT students you must clear the aptitude they will definately select you no doubt about that, TCS is now in hungry mode..:)

    I belongs to non-IT streams so, for non-IT students you must clear the aptitude and please make good knowledge about DS and C( loop, if-else, switch, struct-union, and most important pointer, function array, recursn  file is not needed but u have to know the libery functions used in file), and also make good knwldge about your stream subjects they ask you a lot of question from that and yeah final year project it's important most boss and whenever you gave any answars give it with a 100% confidence, so think before what you are going to say  and whenever you feel you are in a trap just make a good smile dont loose your confidence.

    For Aptitute : please visit the touch-stone question paper from freshersworld and please don't memorize the answer of the question, do solve the question, please know how to solve the problem because there was a lot of question which are similar but the data may change so the answer became diffrent, so be carefull about that. The aptitude based on mostly probability(6-7 q), age(4-5 q), avg (2-3 q), permu-combi(2 q), straight line(1 q), some resng type(3-4 q), area(2 q), train (1 q), time work (1 q), prft-loss( 1 q) etc etc.
    So please go through touch-stone plus R.S. Aggarwal..
    Note that:
    There is negative marks of .33 so plz avoid guessing...try to give ans atleast 20.

    I have done only 19 problems out of 35, but i am very much sure that all i made were 100% right. In last 5 min i did not solve any problem but still i holded my nerve and didnot make any guess, all my friends made 23-24 questions even one of my friend did 28 questions, at that time i was very much depressed, i thought i need to solve one more problem. But when the result was announced i have cleared the aptitude and some of my friends who solved more question than me unfortunately not cleared the aptitude just because of they made some guesses so my suggestion is that please don't make any guess.

    After that there is a form fill-up part, and next the my interview was held, truely speakng friends i could not sleep at that night and going to the interview hahahha. Sometimes i felt i was sleeping just before the interview gonna start, but when my name was announced for the interview i wake up from sleep and entered to the room to panel 9.
