Section 2: General Quantitative Questions on Avg., Time and Distance, Speed, Simple Interest.

This section also had 17 questions

Note: Only one question was displayed at a time for 2mins 14sec for both Sections. We cant go to or fro to any other question. Nor we can we transfer one questions time to another. So utilize your time sensibly. So logically Aptitude part was for 34 questions each for 2mins 14 sec was for 75mins approx. (No sectional cut-off)

Result was declared after Two hours.

2) Written Communication: It was 15mins test. In this a passage was given and we have to brief it into 6sentences exactly in our own words. Use vocab , concentrate on tenses, grammar and correct spellings.

Result was declared after 3hours.

3)GD: Most interesting part for me, cos my group had 15girls including me, so messy. This sections was for 15mins to discus among the group members.

Topics were : 1) Does management should be included into engineering

2)Credit cards: Its uses and abuses.

We choose topic 1, good thing about this was at the end of 15mins, each 1 is given a minute to conclude. That was the time I spoke. This saved me.

Result after half an hour; and good thing my entire group was selected. Day ended at 2100hrs

Day2:

Logical Puzzles reasoning:

This section contained Four questions without options and we had to write the answers with step by step explanation. Students whose answers are correct and explanation was satisfactory were directly send to

HR (Technical Skipped).

I remember all questions.

• 3,12,24,33,66,?
• One train is leaving from Delhi to Mumbai at a speed of 85km/hr. At the same time, another train from Mumbai is heading towards Delhi at 100km/hr. A bird is sitting on top of one train before it commutes. When both train starts their journey,fly flies at 125km/hr. And when it meets opposite it reverts its position and flies until it meets first train. This process is continued until it gets crushed between two trains. How much distance the bird travels in whole journey ? (Refer R.S.Agarwal)
• There is an opening into a firm for one position and there are two applicants for this position. The recruiter finds both applicants useful so he hires both of them on a salary of Rs.2000/yr. He offers both applicants an raise in salary after they pay Rs. 1000 half year. He puts an option for both of them of Rs.100 raise half year and Rs. 300 yearly. 1st person chooses Rs. 300 and 2nd chooses Rs. 100. Who will the gainer and by how much?
• There are 10 friends, each individual has some message. How many minimum telephone calls will be needed, so that evry1 has all messages?

Result was declared after 4 hours.

5)Technical:

• Tell me About Yourself?
• Project?
• Uniqueness of Project?
• Explanation of Answers of Fourth round i.e Logical reasoning. So don’t bluff answers in 4th round?
• Concepts of C? e.g Can we have nested structures and functions? Technical person had lappi wit net connection, he showed one C program and told me to find errors if the program has any, and predict the output and explain the program
• My friends were asked for DBMS, OOPs, Networking,etc.

I was last in my group so I got my result within 10mins

HR

• Tell Me About Yourself?
• You are elder in Your family so due you find any advantage of being elder?
• Asked me to rate myself for logical, analytical and programming skills?
• Gave program to solve, If you have to choose a no. from 1 to 1000, what logic will you apply?
• Ready to relocate (Mainly asked to gals)?
• Any questions

Out of all six rounds my HR was best and he was impressed by me. Result immediately declared as “SELECTED” yeah .

3i Infotech Placement Paper Pattern

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.

* If this doesn't compile, why didn't it (or will it compile?) Don't show comments, which explain the problem.

template void HashTable <>::dummy()
{
K* k = NULL;
Hashable* h = k; // If this fails to compile, it's because
// K is not derived from Hashable.
}

* This will loop forever. Why? Will it really loop forever? (Answer: Base:func() does not call Base::func(). Base: is just a label, so the line always will call Derived::func() until it runs out of stack space)
class Base {
public:
Base() {}
virtual void func() { /* do something */ }
};

class Derived : public Base {
public:
Derived() {}
virtual void func()
{
Base:func();
/* do something else */
}
};
main()
{
Derived d;
d.func(); // Never returns!
}

More advanced questions:

* What is a vtbl ?
* What is RTTI and why do you need it?
* How do I specialize a template? Give an example.
To separate sheep from goats (for those claiming C++ Guru status):
* What is a partial template? Why would you use one?
* How to I create a binary functor in the STL?
Given the following code:
class A;
class B;
class C {
A* a_;
B* b_;
public:
};

Implement a copy constructor and assignment operator for C. A sample solution is something like:
class C {
A* a_;
B* b_;
void swap(C& rhs) { rhs.a_ = a_; rhs.b_ = b_; }
public:
C(const C& rhs) {
auto_ptr<> a(new A(rhs.a_));
auto_ptr<> b(new B(rhs.b_)):
delete a_;
delete b_;
a_ = a.release();
b_ = b.release();
}
C& operator=(const C& rhs) {
C temp(rhs);
temp.swap(*this);
return *this;
}
};

What is wrong with this class, assuming that this is its complete interface?

class C {
char *p;
public:
C() { p = new char[64]; strcpy(p, "Hello world"); }
~C() { delete p; }
void foo() { cout << "My ptr is: '" << p << "'" << endl; }
};

Since this has an overtly programmed destructor, the member wise semantics for destruction are not good enough; therefore, they are not good enough for copy and assignment either. But, the copy ctor and op= are not programmed, so we will have some serious trouble.
Gradual hinting: what happens when we make a copy? [correct answer: pointer is copied]. Now, the original goes out of scope, what happens to the copy? [pointer dangles]. How would you fix it?
[also, that delete p should be delete[ p since p was allocated with the array new]
Assuming that swap() and copy construction are part of your interface for class C, what's the cookie-cutter pattern for operator= that uses them?
answer:

C& C:perator=(const C &rhs;) {
if (this != &rhs;) {
C tmp(rhs);
this->swap(tmp);
}
return *this;
}

Amazon->written test. 
They concentrate on every field of computer science. They asked c,data structure,TOC(context free and context sensitive grammar,regular languages). DBMS unix was not there.
There were two subjective questions.
1. The first one was "given two lists write a function which returns a list which is the intersection of the two lists.the original lists should remain same. (Intersection - if first list is say,1,20 3,45 and second list is 3,24 ,45,90,68 then intersection should be 3,45 )
2. The second was given two nodes of a binary tree find the closest ancestor of the two nodes.
Note:consider binary tree and binary search tree also.
In short answer type questions, the questions were - 
1.There was an aptitude's question in which P(A) and P(B) were given and we had to find P(B/A) and P(A/B) when A and B are independent events.
2.What is the probability that the the 4 digit's no. which is formed by using the digits 1,2,3,4,5,6 is divisible by 4.
3.What tree traversal gives the no. in sorted order. Inorder, preorder or postorder ?
4.Preorder and inorder traversal was given and we had to find the tree.
5. Which sorting algorithm takes best and worst time complexity as O(nlogn)?
6.A dbms query was asked to find the second largest no. of book sold.(i don't remember the question exactly)
