I am APARAJIT MAZUMDER of Radiophysics and Electronics [Electronics and Communication] department of Rajabazar Science College. I am sharing my experiences of joining TCS as nicely as I can.
1> APTITUDE has 3 sections
a. VOCABULARY: [10 antonyms.10 synnonyms,1 fill in the blank, with 5-6 blanks, 5-6 passages with one qs from each]
synonyms, antonyms: learn only the words from tcs papers, don't try to learn from barrons it will be useless and tiresome, learn from tcs papers and u will have a general idea, then u will get at least 5 common in each. take the words from tcs papers. specially follow the recent papers, like the ones uploaded say, 2 days before your exam.. there were 10 synonyms and 10 antonyms.
Fill in the blanks: this is very very easy.. u can do it there itself, only one big fill in the blanks will be given, u will have to choose the correct answers.
Passage reading: about 4-6 passages were given. it is a great mistake to waste time reading them. because there will be a 1 page long passage and only one qs on it to follow [I am not mentioning here about the critical reasoning, that will come later on]. So, for this section basically u only need to prepare the antonyms and synonyms, only reading for a week or so will do, don't have to learn the words by heart ,try to understand the meaning from dictionary etc, and prepare your self in such a way that u will be able to recognise the correct answer from the given options. a sound knowledge of eng will help u.
I am giving here a collection of all possible TYPES of sums, these sums will not come, types of these sums will come, so don't get tensed when u see diff figures in the paper. And another thing, many answers are wrong, meaning, the correct answer will not be there in the options given. mark whichever u like then, and don't ever be afraid to mark a 'none of these' etc. or u can also mark the nearest possible answers in case of wrong answers given.
In the qs booklet the answers were already marked [this applies to all the sections, do not get induced by those answers, because most of them are wrongly done, let your own mind work the problems out] an be prepared to do some new sums in the hall.
You can find model questions at::
c. CRITICAL REASONING:
Learn the answers of this passages from barrons 12 th edition[download for free from www.esnips.com].only 12th edition is usefull.dont go for anything else.u will get these from the model test papers at the end.learn the answers and not the options.meaning,do not learn like:ABCD,learn the options on the whole ,like motorist answer is:toll free highway,toll free highway,traffic conditions, etc… u will get atlest 2 common from these.
The list is:
Model test 1: Section5 - qns 1-4 (motorist), qns 13-16 (red and brown)
Section6 - qns 1-4 (conservative,democratic), qns 8-11 (latin, sanskrit), qns 12-18 (joe, larry, ned), qns 19-22 (a causes b)
Model test 2: Section1 - qns 19-22 (wallachia and rumelia) ---
Section6 - qns 8-12 ( ashland , liverpool), qns 13-16 (spelunker) ---
qns 17-22 (pesth) ---i got this one too
Model test 3: Section6 - qns 1-4 (all Gs are Hs)
Model test 4: Section5 - qns 8-11 (horizontal row), qns 19-22 (a,b,c cause d)
Section6 - qns 8-12 (spanish, italian), qns 13-16 (all As, Bs), qns 17-22 (progressive federal party)
Model test 5: Section3 - qns8-11 (museum), qns 19-22 (A is the father)
Section7- qns 1-5 (prahtu, brahtu), qns 21-25 (scurvy)
I will first share my interview experience: I had a tech + hr interview
Int: tell me about yourself
Me: told, name, present course of study, previous courses, where I live, an about my hobby, that is story books.
Int: which story book have u read recently?
Me: angels and demons by dan brown,and my laugh comes last by JHC
Int: u r from elec. And communication stream,why IT ? u would get a job in Motorola etc easily….
Me: sir,I am interested in computers.[this was a mechanical ans and he caught it right there!!!]
Int: u interested in computers,?? What do u know abt computers?
Me: sir I know basics of c prog and I know hoow to work in windows xp etc
Int: do u know,what is inside a computer ?
Me: I tried to draw a diag connecting a processor to memory and an I/O device.
Int: will the memory beconnected directly to the I/O device?
Me: no sir there will be some buffers.
Int: what kind of buffers?
Me: sir…it would be a memory element as well…
Int: can u name it ?
Me: I smiled and looked at him..i could not name the thing
Int: ok,do u know what memory is made of?
Int: draw register
Int: what is reg made of?
Int: defn of FF?
Int: draw TT of sr ff.
Int: ok can u xplain data storage process in registers ?
Me: xplained by 3 ff's
Int: ok , in yr cv u have mentioned about 2 subjects of interes, communication principles and electronics.which one should I ask first?
Me: digital electronics[told after a bit of hesitation]
Int: what is diff between pnp and npn transistor ?
Int: how does a transistor go to saturation ?
Int: how will u design a transistor such that it does not go to saturation?
Me: told by explaining the biasing equations.
Int: what is mobile communication principles ?
Me: explained the gsm architecture.
Int: what is packet switching ?
Me: sir,we are having this subject in this sem,we have not yet learned so much
Int: ok, ok now madam will ask u some C prog qs…
Int: compare 2 arrays ?
Me: hesitated, told that I did not learn so much of c as yet too write a complete prog to compare 2 arrays.
Int: no, no, u just need to explain the principle and draw a flowchart to xpalain it ?
Me: done it reasonably wll,but with a single small mistake in the flowchart. they did not mind it much and showed me the mistake.
Int: ok, why are u joining tcs ? there is infosys etc ?...
Me: sir , if I jon tcs, then I am joining the tatas .,and I want to join the best….
Int: u r from electronics stream and in tcs u could end up developing a prog for a bank…will u not ge frustrated then ?
Me: sir, this is wor after all., in what form it may be….i'd like to do it…
Int: [appreciated]are u mobile ? u r the only child,,, will ur mother not be sad and all after u leave wb and go outside ?

Me: me,smiling,said a thnk u
