3i Infotech Placement Paper 2006 (Interview & GD)

Group Discussion:

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

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

Here they are short listing ruthlessly around 50%..only 5 members were short listed 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 members 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 at least 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 don't 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 strengths?
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 haven't told any thing about until i asked about it. Now i am a bit disappointed about what they said about the bond

3i Infotech Placement Paper Pattern Held On 28 JAN

The paper was prepared by INSTITUTE OF BANKING PERSONNEL SELECTIONS-MUMBAI.

Aptitude Written Test (Total time: 90 Min, 150 questions)

Section-1 English Language Ability (50 questions)

Section-2 Quantitative Aptitude (50 questions)

Section-3 Logical Reasoning (50 questions)

All 150 questions are given in the beginning, and you can attempt any section at any time. There is individual cut-off in each section. Negative marking 0.25 marks for each wrong answer.

Section- 1:

Q1-15: Comprehension, Antonyms, Synonyms There is a big paragraph (one full page) about regularization of banking acts, etc.

Q1-9 are based on the content of the paragraph.

Q10-12 are Antonyms for some words appeared in the paragraph.

Q13-15 are Synonyms for some words appeared in the paragraph.

Q16-20 (Incomplete Paragraph about Development and Education in Punjab and U.P. was given) In these questions, we need to insert the appropriate word from the options given.

Q21-25: (Ordering sentences in a paragraph) There are 5 Sentences given. They have asked for the correct sequence of those sentences. For example the asked question is which sentence is 2nd? 3rd? etc.

Q26-35: (Sentence improvement) There are 10 sentences. A part of the sentence is in bold part. From the options, we need to improve the meaning of the sentence.

Q36-45: (Identifying error in the sentence) Each Sentence was broken in to 5 parts. We need to find out which portion is having error. Sorry I forgot the other 5 questions.

Except the questions 1-9, I answered all confidently.

Conclusion: Practice Comprehension more, because reading the paragraph itself will take10-15 min. Then answering questions is too difficult.

So, go for other questions which are relatively simple and you feel comfortable.

Section- 2:

Quantitative Aptitude: ( R.S.Agrawal level, but time is very crucial) I am giving you, the topics covered.

1.Compound interest (1q)

2.Simplification (10q)

3.Data Interpretation(15q)

There are 3 Tables and each table comprises of 5 questions.

4.Series Completion (5q)

5.Squre root (1q)

6. Trains (1q)

7.Probability (5q)

Actually I overlooked the other 7 questions, because I have answered only 25 in 30 min. Then I moved to other section. There is no time to see any question 2nd time. So, do it right first confidently. Some questions are (none of these) options type. So doing confidently first time is important.

Do not check your calculation if u get none as your answer. Because they will test confidence by putting none option.

Conclusion: Do all questions in R.S.Agrawal atleast once to get confidence. Emphasize more on DI, Probability. Questions are simple but managing time is imp.

Section- 3:

Logical Reasoning :

Two puzzles on seating arrangement of students- 10q. These puzzles are simple.

example: There are 10 students, five will sit in Row A, and others in Row B. K will sit in between D and E. M is not interested to sit at the end in a row……. like that conditions will be given, Accordingly we can arrange.

Statements and Conclusions- 5q.

There are 4 statements, All cats are dogs, some dogs are squirrels. No Squirrel is Dove. Some doves are cats. etc . Then 3 conclusions were given. and we need to identify which are following. This question is not correct. DO not try to solve it. Just to have an idea I have mentioned.

Blood relations (5q)

The model is like this: A+B means A is brother of B

A-B means A is mother of
AxB means A is father of B

A/B means A is sister of B

Then what will be p+q-r? etc. Please refer R.S.Agrawal Blood Relations Type 3 Coded Relations. (P.NO.237)

Coding & Decoding (7q)

For the numbers 0-9, They have given some letters as their codes. And if a word starts with vowel then code should start with $ symbol, if a word ends with vowel then code should end with # symbol. etc . Now 5 words were given we need to find out their codes.

Odd man out (1q)

A.27 B.64 C.125 D.512 E.216.

ans b

64 is cube as well as square but the others are only cubes.

Data sufficiency (5q):

Three statements were given and one question was given. To answer this question, we need to find out which data is required from the above 3 statements?

Like this total 5 q were given

New model questions (7q)

Five three digits numbers were given. 1 is added to the first digit of all numbers and 1 is subtracted from the middle digit.

Then QUESTIONS are which is lowest, highest? ect.

Example: 546, 687, 456, 274, 487

After modifying according to the given conditions, 636, 777, 546, 364, 577. Now you can arrange these numbers either ascending or descending order to answer the questions.
