General Tips To Overcome An Interview

So what if you are not a mountaineer. Or a keen hiker. You still cannot treat your interview like a careless morning trot along a jogger's path. Your jaw-jaw at the interview table is nothing less than a cautious climb up a mountain trail--which begins around your early childhood and meanders through the years at the academia before reaching a new summit in your career.And as you retrace your steps down memory lane make sure that you post flags at important landmarks of your life and career, so that you can pop them before the interview panel scoops them out of you. You don't want to be at the receiving end, do you?

Face the panel, but don't fall of the chair in a headlong rush-and-skid attempt to tell your story. Take one step at a time. If you place your foot on slippery ground, you could be ejecting out on a free fall.

So prepare, fortify your thoughts, re-jig your memory, and script and design your story (without frills and falsity). Without the right preparation and storyboard, you could be a loser at the interview. Here are a few preparation tips that books on interviews sometimes overlook.   

                                                        

Before the interview


1. Chronological Outline of Career and Education Divide your life into "segments" defining your university, first job, second job. For each stage, jot down :
The reason for opting certain course or profession; Your job responsibilities in your previous/current job; Reason of leaving your earlier/current job. You should be clear in your mind where you want to be in the short and long term and ask yourself the reason why you would be appropriate for the job you are being interviewed for and how it will give shape to your future course.

2. Strengths and Weaknesses

You should keep a regular check on your strengths and weaknesses. Write down three (3) technical and three (3) non-technical personal strengths. Most importantly, show examples of your skills. This proves more effective than simply talking about them. So if you're asked about a general skill, provide a specific example to help you fulfil the interviewer's expectations. It isn't enough to say you've got "excellent leadership skills". Instead, try saying:

"I think I have excellent leaderships skills which I have acquired through a combination of effective communication, delegation and personal interaction. This has helped my team achieve its goals."

As compared to strengths, the area of weaknesses is difficult to handle. Put across your weakness in such a way that it at leaset seems to be a positive virtue to the interviewer. Describe a weakness or area for development that you have worked on and have now overcome.

3. Questions you should be prepared for                                                                                  

Tell us about yourself.
What do you know about our company?
Why do you want to join our company?
What are your strengths and weaknesses?
Where do you see yourself in the next five years?
How have you improved the nature of your job in the past years of your working? Why should we hire you?
What contributions to profits have you made in your present or former company? Why are you looking for a change?

Answers to some difficult questions :                                     

• Tell me about yourself ?
  Start from your education and give a brief coverage of previous experiences. Emphasize more on your recent experience explaining your job profile.
  
  What do you think of your boss?
  Put across a positive image, but don't exaggerate
  
  Why should we hire you? Or why are you interested in this job?
  Sum up your work experiences with your abilities and emphasise your strongest qualities and achievements. Let your interviewer know that you will prove to be an asset to the company.
  
  How much money do you want?
  Indicate your present salary and emphasise that the opportunity is the most important consideration.
  
   Do you prefer to work in a group?
  Be honest and give examples how you've worked by yourself and also with others. Prove your flexibility.

4. Questions to As                                                                                          

 At the end of the interview, most interviewers generally ask if you have any questions. Therefore, you should be prepared beforehand with 2-3 technical and 2-3 non-technical questions and commit them to your memory before the interview.

Do not ask queries related to your salary, vacation, bonuses, or other benefits. This information should be discussed at the time of getting your joining letter. Here we are giving few sample questions that you can ask at the time of your interview.

Sample Questions

Could you tell me the growth plans and goals for the company?

What skills are important to be successful in this position?

Why did you join this company? (optional)

What's the criteria your company uses for performance appraisal?

With whom will I be interacting most frequently and what are their responsibilities and the nature of our interaction?

What is the time frame for making a decision at this position?

What made the previous persons in this position successful/unsuccessful?

 5. Do your homework         

                                                                                                                    

 Before going for an interview, find out as much information on the company (go to Jobs Ahead Company Q and A) as possible. The best sources are the public library, the Internet (you can check out the company's site), and can even call the company and get the required information. The information gives you a one-up in the interview besides proving your content company or position.

Clearing the interview isn't necessarily a solitary attempt. Seek assistance from individuals who are in the profession and whose counsel you value most. Be confident in your approach and attitude; let the panel feel it through your demeanour, body language and dressing.

Getting prepared for your interview is the best way to dig deep and know yourself. You will be surprised that it would breed a new familiarity become more familiar with your own qualifications that will be make you present yourself better. All the best and get ready to give a treat.

  

Discretion abt written  Selection Process

Written Test:

Prepare from previous papers. It’s of the same pattern.Prepare wordlist from Barrons. There was no psychometric test.We had only 1 and a half hr to complete the paper. For quants, we had to write the answers and were not of multiple choices. Logical questions were bit tough.Main problem is the time shortage to complete it fully.

Interview

 There were around 8 - 10 panels for tech intrw held at TCS, Karapakkam, Chennai.Environment was excellent.

People from TCS were very soft and had a cheerful face.

In my panel, two persons of age around 35 – 40 yrs interviewed me.Tech intrw was held for around 55 min. Slightly drilling but easy.After clearing tech, I attended HR where one young man interviewed me.It went for half an hour exactly.Most of them were only personal questn and some tech Qs.On my time slot, 5 ppl attended in that same panel and only 2 cud get thro.

For another friend, the tech held for just 10min.They asked 2 gen. Qs like where he is from (Ambattur) and how he reached that office.Then 2 tech Qs 1) Shannons theory ? Ans: “I don’t know”2) Diff betn up85 & 86. He told correctly.He got selected.

TCS New Pattern Placement paper 2013 (OpenSeesame)

As you already aware of the fact that TCS has changed the database of questions for its aptitude test.  The questions below give you an overview of the models to be prepared.  But don't depend on these models only.  We solved these questions only as an indicative purpose.  You are requested to go through all the arithmetic topics given in this site so that you become confident of sitting for TCS or any other written test.  All the best... The question below have been taken from https://campus.tcs.com/OpenSeesame/

1.  If 3y + x > 2 and x + 2y$ \le $3, What can be said about the value of y?
A. y = -1
B. y >-1
C. y <-1
D. y = 1
Answer: B

Multiply the second equation with -1 then it will become - x - 2y$ \ge $ - 3.  Add the equations.  You will get y > -1.

2. If the price of an item is decreased by 10% and then increased by 10%, the net effect on the price of the item is
A. A decrease of 99%
B. No change
C. A decrease of 1%
D. An increase of 1%
Answer: C

If a certain number is increased by x% then decreased by x% or vice versa, the net change is always decrease.  This change is given by a simple formula $ - {\left( {\displaystyle\frac{x}{{10}}} \right)^2} =  - {\left( {\displaystyle\frac{{10}}{{10}}} \right)^2} =  - 1\% $.  Negitive sign indicates decrease.

3. If m is an odd integer and n an even integer, which of the following is definitely odd?
A. (2m+n)(m-n)
B. $(m + {n^2}) + (m - {n^2})$
C. ${m^2} + mn + {n^2}$
D. m +n
Answer: C and D (Original Answer given as D)

You just remember the following odd $ \pm $ odd = even; even $ \pm $ even = even; even $ \pm $ odd = odd
Also odd x odd = odd; even x even = even; even x odd = even.

4.  What is the sum of all even integers between 99 and 301?
A. 40000
B. 20000
C. 40400
D. 20200
Answer: D

The first even number after 99 is 100 and last even number below 301 is 300.  We have to find the sum of even numbers from 100 to 300.  i.e., 100 + 102 + 104 + ............... 300.
Take 2 Common.  2 x ( 50 + 51 + ...........150)
There are total 101 terms in this series.  So formula for the sum of n terms when first term and last term is known is $\displaystyle\frac{{\rm{n}}}{{\rm{2}}}\left( {{\rm{a + l}}} \right)$
So 50 + 51 + ...........150 = $\displaystyle\frac{{101}}{{\rm{2}}}\left( {{\rm{50 + 150}}} \right)$
So 2 x $\frac{{101}}{{\rm{2}}}\left( {{\rm{50 + 150}}} \right)$ = 20200

5. There are 20 balls which are red, blue or green.  If 7 balls are green and the sum of red balls and green balls is less than 13, at most how many red balls are there?
A. 4
B. 5
C. 6
D. 7
Answer: B

Given R + B + G = 17; G = 7; and R + G < 13.  Substituting G = 7 in the last equation, We get R < 6.  So maximum value of R = 6

6.  If n is the sum of two consecutive odd integers and less than 100, what is greatest possibility of n?
A. 98
B. 94
C. 96
D. 99
Answer : C

We take two odd numbers as (2n + 1) and (2n - 1).
Their sum should be less than 100. So (2n + 1) + (2n - 1) < 100 $ \Rightarrow $ 4n < 100.
The largest 4 multiple which is less than 100 is 96

7. ${x^2}$ < 1/100, and x < 0 what is the highest range in which x can lie?
A. -1/10 < x < 0
B. -1 < x < 0
C. -1/10 < x < 1/10
D. -1/10 < x
Answer: A

Remember:
(x - a)(x - b) < 0 then value of x lies in between a and b.
(x - a)(x - b) > 0 then value of x does not lie inbetween a and b. or ( $ - \infty $, a) and (b, $ - \infty $) if a < b
${x^2}$ < 1/100 $ \Rightarrow $
$({x^2} - 1/100) < 0 \Rightarrow ({x^2} - {(1/10)^2}) < 0 \Rightarrow (x - 1/10)(x + 1/10) < 0$
So x should lie inbetween - 1/10 and 1/10.  But it was given that x is -ve. So x lies in -1/10 to 0

8.  There are 4 boxes colored red, yellow, green and blue.  If 2 boxes are selected, how many combinations are there for at least one green box or one red box to be selected?
A. 1
B . 6
C. 9
D. 5
Answer: 5

Total ways of selecting two boxes out of 4 is $4{C_2}$ = 6.  Now, the number of ways of selecting two boxes where none of the green or red box included is only 1 way.  (we select yellow and blue in only one way).  If we substract this number from total ways we get 5 ways.

9. All faces of a cube with an eight - meter edge are painted red.  If the cube is cut into smaller cubes with a two - meter edge, how many of the two meter cubes have paint on exactly one face?
A. 24
B. 36
C. 60
D. 48
Answer : A

If there are n cubes lie on an edge, then total number of cubes with one side painting is given by $6 \times {\left( {n - 2} \right)^2}$.  Here side of the bigger cube is 8, and small cube is 2.  So there are 4 cubes lie on an edge. Hence answer = 24

10. Two cyclists begin training on an oval racecourse at the same time.  The professional cyclist completes each lap in 4 minutes; the novice takes 6 minutes to complete each lap.  How many minutes after the start will both cyclists pass at exactly the same spot where they began to cycle?
A. 10
B. 8
C. 14
D. 12
Answer: D

The faster cyclyst comes to the starting point for every 4 min so his times are 4, 8, 12, .........  The slower cyclist comes to the starting point for every 6 min so his times are 6, 12, 18, .........  So both comes at the end of the 12th min.

11. M, N, O and P are all different individuals; M is the daughter of N; N is the son of O; O is the father of P; Among the following statements, which one is true?
A. M is the daughter of P
B. If B is the daughter of N, then M and B are sisters
C. If C is the granddaughter of O, then C and M are sisters
D. P and N are bothers. 
Answer: B

From the diagram it is clear that If B is the daughter of N, then M and B are sisters.  Rectangle indicates Male, and Oval indicates Female.



12. In the adjoining diagram, ABCD and EFGH are squres of side 1 unit such that they intersect in a square of diagonal length (CE) = 1/2.  The total area covered by the squares is

A. Cannot be found from the information
B. 1 1/2
C. 1 7/8
D. None of these
Answer:  C

Let CG = x then using pythogerous theorem ${\rm{C}}{{\rm{G}}^{\rm{2}}}{\rm{ + G}}{{\rm{E}}^{\rm{2}}}{\rm{ = C}}{{\rm{E}}^{\rm{2}}}$
$ \Rightarrow $  ${x^2} + {x^2} = {(1/2)^2} \Rightarrow 2{x^2} = 1/4 \Rightarrow {x^2} = 1/8$
Total area covered by two bigger squares = ABCD + EFGE - Area of small square = 2 - 1/8 = 15/8


13. There are 10 stepping stones numbered 1 to 10 as shown at the side.  A fly jumps from the first stone as follows; Every minute it jumps to the 4th stone from where it started - that is from 1st it would go to 5th and from 5th it would go to 9th and from 9th it would go to 3rd etc.  Where would the fly be at the 60th minute if it starts at 1?
A. 1
B. 5
C. 4
D. 9
Answer : A

Assume these steps are in circular fashion. 
Then the fly jumps are denoted in the diagram.  It is clear that fly came to the 1st position after 5th minute.  So again it will be at 1st position after 10th 15th .....60th. min.

So the fly will be at 1st stone after 60th min.

 

14. What is the remainder when ${{\rm{6}}^{{\rm{17}}}}{\rm{ + 1}}{{\rm{17}}^{\rm{6}}}$  is divided by 7?
A. 1
B. 6
C. 0
D. 3
Answer: C

${{\rm{6}}^{{\rm{17}}}}$ = ${{\rm{(7 - 1)}}^{{\rm{17}}}}$ =
${\rm{17}}{{\rm{C}}_{\rm{0}}}{\rm{.}}{{\rm{7}}^{{\rm{17}}}}{\rm{ - 17}}{{\rm{C}}_{\rm{1}}}{\rm{.}}{{\rm{7}}^{{\rm{16}}}}{\rm{.}}{{\rm{1}}^{\rm{1}}}.....{\rm{ + 17}}{{\rm{C}}_{{\rm{16}}}}{\rm{.}}{{\rm{7}}^{\rm{1}}}{\rm{.}}{{\rm{1}}^{{\rm{16}}}}{\rm{ - 17}}{{\rm{C}}_{{\rm{17}}}}{\rm{.}}{{\rm{1}}^{{\rm{17}}}}$

If we divide this expansion except the last term each term gives a remainder 0.  Last term gives a remainder of - 1.

Now From Fermat little theorem, ${\left[ {\displaystyle\frac{{{{\rm{a}}^{{\rm{p - 1}}}}}}{{\rm{p}}}} \right]_{{\rm{Rem}}}}{\rm{ = 1}}$
So ${\left[ {\displaystyle\frac{{{{17}^6}}}{7}} \right]_{{\rm{Rem}}}}{\rm{ = 1}}$

Adding these two remainders we get the final remainder = 0

15. In base 7, a number is written only using the digits 0, 1, 2, .....6.  The number 135 in base 7 is 1 x ${{7^2}}$ + 3 x 7 + 5 = 75 in base 10.  What is the sum of the base 7 numbers 1234 and 6543 in base 7.
A. 11101
B. 11110
C. 10111
D. 11011
Answer: B

In base 7 there is no 7.  So to write 7 we use 10.  for 8 we use 11...... for 13 we use 16, for 14 we use 20 and so on.
So from the column d, 4 + 3 = 7 = 10, we write 0 and 1 carried over.  now 1 + 3 + 4 = 8 = 11, then we write 1 and 1 carried over.  again 1 + 2 + 5 = 8 = 11 and so on



16. The sequence ${\rm{\{ }}{{\rm{A}}_{\rm{n}}}{\rm{\} }}$ is defined by ${{\rm{A}}_1}$ = 2 and ${{\rm{A}}_{{\rm{n + 1}}}}{\rm{ = }}{{\rm{A}}_{\rm{n}}}{\rm{ + 2n}}$ what is the value of ${{\rm{A}}_{100}}$
A. 9902
B. 9900
C. 10100
D. 9904
Answer: A
We know that ${{\rm{A}}_1}$ = 2 so ${{\rm{A}}_{\rm{2}}}{\rm{ = }}{{\rm{A}}_{{\rm{1 + 1}}}}{\rm{ = }}{{\rm{A}}_{\rm{1}}}{\rm{ + 2(1) = 4}}$
${{\rm{A}}_3}{\rm{ = }}{{\rm{A}}_{{\rm{2 + 1}}}}{\rm{ = }}{{\rm{A}}_2}{\rm{ + 2(2) = 8}}$
${{\rm{A}}_4}{\rm{ = }}{{\rm{A}}_{{\rm{3 + 1}}}}{\rm{ = }}{{\rm{A}}_3}{\rm{ + 2(3) = 14}}$
So the first few terms are 2, 4, 8, 14, 22, ......
The differences of the above terms are 2, 4, 6, 8, 10...
and the differences of differences are 2, 2, 2, 2.  all are equal.  so this series represents a quadratic equation.
Assume  ${{\rm{A}}_{\rm{n}}}$ = $a{n^2} + bn + c$
Now ${{\rm{A}}_1}$ = a + b + c = 2
${{\rm{A}}_2}$ = 4a + 2b + c = 4
${{\rm{A}}_3}$ = 9a + 3b + c = 8
Solving above equations we get a = 1, b = - 1 and C = 2
So substituting in ${{\rm{A}}_{\rm{n}}}$ = ${n^2} + bn + c$ = ${n^2} - n + 2$
Substitute 100 in the above equation we get 9902.

17.Find the number of rectangles from the adjoining figure (A square is also considered a rectangle)

A. 864
B. 3276
C. 1638
D. None

Answer: C

To form a rectangle we need two horizontal lines and two vertical lines.  Here there are 13 vertical lines and 7 horizontal lines.  The number of ways of selecting 2 lines from 13 vertical lines is $13{C_2}$ and the number of ways of selecting 2 lines from 7 horizontals is $7{C_2}$. So total rectangles = $7{C_2}x13{C_2}$

18. A, B, C and D go for a picnic.  When A stands on a weighing machine, B also climbs on, and the weight shown was 132 kg.  When B stands, C also climbs on, and the machine shows 130 kg.  Similarly the weight of C and D is found as 102 kg and that of B and D is 116 kg.  What is D's weight
A. 58kg
B. 78 kg
C. 44 kg
D. None
Answer : C

Given A + B = 132; B + C = 130; C + D = 102, B + D = 116
Eliminate B from 2nd and 4th equation and solving this equation and 3rd we get D value as 44.

TCS On line Aptitude Test

1Aptitude Test ::

You can find so many placement paper on various site on internet. But you can be remain sure that a single one you will not get in Current TCS Aptitude Test. Aptitude test consist of 30 question for 80minutes.

There are 5-6 question from “Time & Work(lengthy calculation)”. And the rest of the question you can’t be guessed. In my question They were from volume & surface area, average, profit & loss, partnership, probability. But may be different in your test. Many question were too much lengthy to read. They consumes 1-1.2min just to read in.

So my suggestion is that do practice as much as possible from “Dr.R.S.Aggarwal Quantitative Aptitude”.

Now If you can clear the Aptitude Test, you are eligible for the next round..

2Technical Interview(1^st round) ::

First 30 min there was only 1 interviewer in my panel. After 30min one another joined with him..
