Interview/campus/HR/placememnt questions - Why should I hire you?

Interview/campus/HR/placememnt questions - Why should I hire you?


Question : Why should I hire you?

Most of the companies ask this question so now this question is open for all of you.
Add your comments/Answer about this question.

Use comments link available in the last of this post.

Suggested Answer: The easy answer is that you are the best person for the job.
And don’t be afraid to say so.
But then back it up with what specifically differentiates you.

For example: “You should hire me because I’m the best person for the job. I realize that there are likely other candidates who also have the ability to do this job. Yet I bring an additional quality that makes me the best person for the job--my passion for excellence. I am passionately committed to producing truly world class results."

All The Best

How would you describe yourself?

How would you describe yourself?



"Describe yourself" this is most likely question which asked in personal interview. So what do we say?
Frankly, just answer the question as it comes but don't answer like this
"Sir basicly , my name is xyz. My father's name is...."
Why don't we realise that our CV is there right in front of the interviewer, and he knows this already.

Actually, a question of this kind is an ideal way to plug in everything we want to say about ourselves that we had leave out of the CV. If you have attended a premier institution, say that the institution taught you much more than the degree it awared ypu, mention people who influenced ypu, talk about the books you like reading, your hobbies and your other interests.

Talk about your strengths; perhaps mention an instance when you used your conflict resolution skills or selling skills or whatever. But make certain that it does not sound like blowing your trumpet. Mention these instances as learning.

Tall about your weaknesses, but make sure that they are 'positive' weaknesses. For instance you could say that that you sometimes pay more attention to detail than is warranted. You can openly confess a tendency to be impatient with team members who cannot carry their own weight, or who cannot contribute sufficiently.

But first, think today what you want to say and practice.

Interview/campus/HR/placememnt questions - What is your greatest weakness

Interview/campus/HR/placememnt questions - What is your greatest weakness





What is your greatest weakness?

Answer : Most career books tell you to select a strength and present it as a weakness. Such as: “I work too much. I just work and work and work.” Wrong. First of all, using a strength and presenting it as a weakness is deceiving. Second, it misses the point of the question.

You should select a weakness that you have been actively working to overcome. For example: “I have had trouble in the past with planning and prioritization. However, I’m now taking steps to correct this. I just started using a pocket planner . . .” then show them your planner and how you are using it.

Talk about a true weakness and show what you are doing to overcome it.

12. Which system tables contain information on privileges granted and privileges obtained?
USER_TAB_PRIVS_MADE, USER_TAB_PRIVS_RECD

13. Which system table contains information on constraints on all the tables created?
USER_CONSTRAINTS

14. TRUNCATE TABLE EMP;
DELETE FROM EMP;
Will the outputs of the above two commands differ?
Both will result in deleting all the rows in the table EMP.

15. What is the difference between TRUNCATE and DELETE commands?
TRUNCATE is a DDL command whereas DELETE is a DML command. Hence DELETE operation can be rolled back, but TRUNCATE operation cannot be rolled back. WHERE clause can be used with DELETE and not with TRUNCATE.

Operating system (OS) questions placement / aptitude / interview/assessment/multiple choice/career/campus

Operating system (OS) questions placement / aptitude / interview/assessment/multiple choice/career/campus



OS question
1. Explain the concept of Reentrancy.
Answer: It is a useful, memory-saving technique for multiprogrammed timesharing systems. A Reentrant Procedure is one in which multiple users can share a single copy of a program during the same period. Reentrancy has 2 key aspects: The program code cannot modify itself, and the local data for each user process must be stored separately. Thus, the permanent part is the code, and the temporary part is the pointer back to the calling program and local variables used by that program. Each execution instance is called activation. It executes the code in the permanent part, but has its own copy of local variables/parameters. The temporary part associated with each activation is the activation record. Generally, the activation record is kept on the stack.
Note: A reentrant procedure can be interrupted and called by an interrupting program, and still execute correctly on returning to the procedure.


2. Explain Belady's Anomaly.
Answer: Belady's Anomaly also called FIFO anomaly. Usually, on increasing the number of frames allocated to a process' virtual memory, the process execution is faster, because fewer page faults occur. Sometimes, the reverse happens, i.e., the execution time increases even when more frames are allocated to the process. This is Belady's Anomaly. This is true for certain page reference patterns.

3. What is a binary semaphore? What is its use?
Answer: A binary semaphore is one, which takes only 0 and 1 as values. They are used to implement mutual exclusion and synchronize concurrent processes.

4. What is thrashing?
Answer: It is a phenomenon in virtual memory schemes when the processor spends most of its time swapping pages, rather than executing instructions. This is due to an inordinate number of page faults.

5. List the Coffman's conditions that lead to a deadlock.
Answer:
1.Mutual Exclusion: Only one process may use a critical resource at a time.
2.Hold & Wait: A process may be allocated some resources while waiting for others.
3.No Pre-emption: No resource can be forcible removed from a process holding it.
4.Circular Wait: A closed chain of processes exist such that each process holds at least one
resource needed by another process in the chain.

INTERVIEW QUESTIONS for placement / aptitude / interview/assessment/multiple choice/career/campus


Technical Questions in the second round –

—————————————

[1] What are the current trends and areas of focus in IT.

My Ans. Talked about emerging trends of S/W Engg and ISO 9000 stuff

(gave vague ideas about them as I don’t know much nor do I care

about these topics myself ;-)). Then mentioned the proliferation of O-O

methodologies and their usefulness in speeding up development process,

code re-usability, ease of maintenance, ease of bug-fixing.

Thirdly, mentioned the work going on in High-Speed N/w - FDDI, ATM,

Fast-Ethernet(100Mbps). Told whatever little I knew about ATM in

response to another question.

[2] What is a Micro-Kernel architecture.

My Ans. This is a developing area in OSs where instead of building the

kernel as a single monolithic structure starting from scratch, it is

built as a set of layers. The micro-kernel provides only the bare-bones

like Device-drivers, rudimentary filesystem support etc. on which,

depending on the intended area of application of the OS, it can be

customized to provide various higher level OS features like

Multiprocessing, IPC, etc.

Personal Questions in the second round –

————————————–

1. Tell us about yourself, your background.

2. What does your father do currently.

3. Your performance in schooling, B.E.

4. Your +/- points.

5. Why do you think Wipro should take you.

6. What qualities do you have that make you a person suitable for going

into the IT industry (a corollary to the previous question).

7. What do your friends opine about you.

8. When do you think you will complete and be able to join.

9. How can you assure that you will join by that time.

10. Anything you want to know about us.

} /* End of for() */

a) Describe the memory management policies in Unix. How is paging

implemented? How page faults are handled?

Seems to be a favorite question for these chaps —- Maurice Bach.

b) Write a macro in C for swapping two nibbles in a byte.

-Use the shift operators and be careful while defining temporary

variables( if you do so) as you have to write a macro. Otherwise

it is pretty simple.

c) What is the CPU-scheduling policy in Unix? - Round robin scheduling

with multilevel queues.

d) Diffrence between short term, long term and medium term scheduler.

-First two should be peaceful. The last one is also known as

swapper. (See Taenenbaum and/or Peterson)

e) Name various page-replacement policies. Which can be implemented

both with and without pre-emption? - see Peterson.

f) Describe the Sliding window protocol. What is it’s advantage

over stop-and-wait? - Saves bandwidth. (Taenenbaum please)

2ND INTERVIEW (Both personal and technical interleaved)

a) Tell us something about yourself.

b) Aren’t you going for higher studies abroad? Why?

c) Rank and CGPA. MSites do not have ranks but still they wanted to

know my approx position in my batch.

- Shady question. It is your job to convince them that for

MS, grades do not hold any meaning.

d) What is re-entrant code? — Non-self modifying code. Can be

shared by many processes simultaneously. Gave e.g. of text-editors

like ‘vi’.

Counter Q: But then no code modifies itself. What does ‘non-self

modifying’ mean? —- I don’t know for sure.

e) Diff between compilers and interpreters. Some fundaes about

how to link code in different files.

f) What would your friends tell us about you if we ask them?

Standard question for everyone.

Second interview: (fully personal) — This was more interesting;-)

a) What did you feel about the ppt? — wasn’t very impressive

so gave some shady answer.

b) Have you heard of creativity? — Ya.

Have you heard of Bernard Shaw? — Ya.

(Then he rattled off some quote of BS regarding creativity)

What do you say? — I put some shadiest fundaes regarding

visionaries and Leonardo da Vinci conceptualising Helicopters

in his time!
