3I INFOTECH PAPER ON JANUARY AT DELHI


So looking for a job in 3i.. well if yes then dont worry at all for apti n all. On 28th of jan , i wrote 3's paper. Now i m going to describe it--
There was 3 sections- English usage, Logical Reasoning and arithmetic n data interpretation There was i total 150 q's, having 50 q's from each sections. All Q's were easy.

Time limit : 90 mins 
Before going to venue, just read out the instructions given on the site, coz there was lot of confusions. I did keep with me the specimen answer sheet.

Section 1: English usage
In this there was a paragrap, nearly 400 words, about regularization of banking acts. On basis of this para there was q's . These are as follows-
--> 10 direct q's relataed to para
--> 3 Synoyms(Contemporay, Resilence etc.)
--> 3 Antonyms
--> 9 q's were based on fill in d blanks which was nothing bt, about Development and Education in Punjab and U.P.

on an aveage all d synonyms n antonyms were very easy and day to day conversational use. These synonyms and antonyms were given in bold in d para.
While solving this type para plz keep in mind that one time reading with better comprehension is nt only helpful, bt u have o use regression. Remaining 25 q's were based on finding out grammatical error(u can see in any cat/ mat preparartion book). On these some were diifficult.
In this section i did only 23 q's.

Section 2 : Reasoning
--> 1 caselet based sitting arrangement(5-6 q's)
--> 5 q's based on Blood Relation(if A+B stands for A is father of B , A-B stands for Ais bro of B......... then what is A-B*c so on )
--> 5 q's based on critical resoning(like all banana's are mango, some mangoes are chilli then conclude...)
--> 4-5 q's based on series. In this you have to find out odd one in he series.
--> Some on coding decodg
--> Some were slightly different. These were like -- 5 different nos were given and said that 1 is added to the first digit of all numbers and 1 is subtracted from the middle digit. then Find out the second largest n so on.
--> Some were Data Sufficiency
Suggestion: For seies go through Mtyra's Book Quicker maths.

Section 3 : Arithmetic
In this topic on which Q's were based, is as -
1. Probab -- 5 q's, in this q like--- there are different balls in a bag as3-green, 5-blue, 7-red. 6-black then find out the probab of getting 2 red balls, gtting at least 1 gren ball while picking up 3 balls n so on.

2. Series Comletion- 5 q
3. Simplification-10-12 q, as (1) if 12.48 / ? / 56.4 = 12.3 then find ? and so on
4. Compound Interest -1q (Direct Formula)
5. Trains speed-1q as, A train crosses a platform of length double of its length, in 30 sec. Find speed of train.(Ans- can not determined)
6. Data Interpretation- 15 q, 2tables and 1 pie chart, vey easy just calculation basis.

Do as much as possible Bank po sets, there is nothing bt all depends on UR CALCULATION SPEED. So start mental calculation from today it will help u in this and other papers as well. Andd dont forget to pray for me I m waiting for call...

3i Infotech Job Interview Placement Paper 2006

Group Discussion

The topics are very general ,there is absolutely no need for preparation.
Topics for my and next group are like

Can a person be in politics and be clean as well?
Is attendance mandatory in the colleges?

Here they are shortlisting ruthlessly around 50%..only 5 members were shortlisted in my group of 10..same for the next group...so express your opinion and be in discussion.
There are no moderators for the discussion we have to moderate ourselves..
and have to take chances to express ur opinion..no right or wrong answers!.Hope u can.

The interview is scheduled for afternoon at 1:30..and there is no time keeping from the interview panel side..they came in 2:30 in a relaxed state leaving us standing for one hour without any chairs. Everyone who got selected is nervous about the interview.No one still know whether it will be technical or general.

About the interview

Only 2 memebers are there in the interview panel. I entered into the room and they offered me a seat and asked me for my resume and the interview printout.I handed it over to the guy.
He looks into my resume and asked me ..

1) what is your qualification?
My answer: XX from X university
I guessed: Anyone who looks at my resume should ask one more question, or atleast show interest in the qualification..because that is different..but nothing happened

2) Can you introduce yourself?
My answer: I told what i am doing curently..as i am experienced...and how i can fit ito the job..
My guess: they are expecting a very traditional answer...like i am Mr X..finished X degree and blah blah about personal details.

3)How can you relate your experience to the IT field?
My answer: I had experience in financial services..and told them how it is useful to the company as 3i is also in the same domain offering its products and services.
My guess: They seem to have no idea about financial services and the type of work i am doing .. so a bit not satisfied.

4)Have you done any IT courses?
I told them what i have done..i have done an ERP course panel response: I dont think there is nothing to learn in the ERP
My guess:If you know C++, Java then only they feel it is an IT course.

5) what are your strenghts?
I told what i got..including the transferable skills which i can bring from my previous job..
My guess: They are looking for hardcore technical skills

6)Do you have any questions?
I told Yes..and asked them about the training programme and the bond details..
they havent told any thing about until i asked about it.
Now i am a bit disappoined about what they said about the bond
