You could had prepared well for interviews, you could literally be aware of every question that would be fired upon you in an interview, you could had completed your placement test successfully well, but during the interviews most of the students tend to get nervous. If you can cover up your nervousness and if you can still answer the questions well, then it might do good. But, in most cases, nervousness affects your ability to listen well. When you fail to listen well, the chances are that you performance could degrade as well. Knowing the root cause of this unusual nervousness can get you to overcome this feeling.

This arises due to the fear of getting into embarrassing situations. Several CV readers do mail us about this problem and among them 9 out of 10 would fall int...

Below are three questions on numbers on concepts dealing with odd and even and a new class called "even-odd" numbers. Question 1 If n is an even-odd number then which of the following must be false? (A number is called "even-odd" if it is halfway between an even integer and an odd integer.) a) n/2 is not an integer b)(2n) 2 is an integer c)4n is an odd integer d)none of these Answer : c)4n is an odd integer Solution: A number is called "even-odd" if it is halfway between an even integer and an odd integer. For example, consider an even integer 10 and an odd integer -5. Number halfway between them will be (10 - (-5)) / 2 = 7.5. Here 7.5 is an "even-odd" number. i.e., an even-odd number will be in the form x + 1/2 = x.5 where x is any integer. Let us see with each option: Consider option a : Since n is a fraction number then n/2 is also a fraction. i.e., n/2 is not an integer. Hence option a is true. Consider option b :...

Question 1 (In DBMS like Oracle) Which of the following allow null values ? A Unique Key or Primary Key ? Answer : Primary Key constraint does not allow null values to be inserted while it is legal in case of Unique key. Question 2 Considering an Oracle database as an example, can NULL values be used in arithmetic operations ? Explain your answer ? Answer : No, NULL value cannot be used in arithmetic operation. This is because a NULL just denotes an 'absence' of information rather than 'empty' or 'zero' value. Question 3 How you can delete a duplicate row from Unique key column? Answer : This necessity does not arise. First of all Unique key column will not allow duplicate rows to be inserted. Question 4 Tell any one advantage of using stored procedures in applications? Answer : Stored Procedures abstract complex SQL queries from application code. For example, a task involving multiple lines of complex SQL queries can be simpli...

Thrashing is said to occur when the system spends a large amount of time transferring shared data blocks from one node to another, compared to the time spent doing the useful work of executing application  processes. It is serious performance problem with DSM systems that allow data blocks to migrate from one node to another. Thrashing may occur in the following situations: a.  When interleaved data accesses made by processes on two or more nodes causes a data block to move back and forth from one node to another in quick succession. b.  When blocks with read-only permissions are invalidated soon after they are replicated. Following methods may be used to solve the thrashing problem in DSM systems: a.  Providing  application-controlled  locks.  Locking  data  to  prevent  other  nodes  from accessing that data for a short period of time can reduce thrashing. b.  Nailing a block to a node for a minimum amount of time....

Full form of CLR is Common Language Runtime and it forms the heart of the .NET framework.All Languages have runtime and its the responsibility of the runtime to take care of the code execution of the program.For example VC++ has MSCRT40.DLL,VB6 has MSVBVM60.DLL , Java has Java Virtual Machine etc. Similarly .NET has CLR.Following are the responsibilities of CLR √ Garbage Collection :- CLR automatically manages memory thus eliminating memory leakes. When objects are not referred GC automatically releases those memory thus providing efficient memory management. √ Code Access Security :- CAS grants rights to program depending on the security configuration of the machine.Example the program has rights to edit or create a new file but the security configuration of machine does not allow the program to delete a file.CAS will take care that the code runs under the environment of machines security configuration. √ Code Verification :- This ensures proper code execution and ty...

Question 8    Aren’t you overqualified for this position? TRAPS:   The employer may be concerned that you’ll grow dissatisfied and leave. BEST ANSWER:   As with any objection, don’t view this as a sign of imminent defeat.  It’s an invitation to teach the interviewer a new way to think about this situation, seeing advantages instead of drawbacks. Example:   “I recognize the job market for what it is – a marketplace.  Like any marketplace, it’s subject to the laws of supply and demand.  So ‘overqualified’ can be a relative term, depending on how tight the job market is.  And right now, it’s very tight.  I understand and accept that.” “I also believe that there could be very positive benefits for both of us in this match.” “Because of my unusually strong experience in ________________ , I could start to contribute right away, perhaps much faster than someone who’d have to be brought along more slowly.” “There’s also the value of ...

Question 7 Why should I hire you?            We have already discussed about this question but still this is also an important, this can help you to understand, what is the TRAP behind the Questions or the reason why the employer is asking the question to you.. as this is the Killer question you are getting the chance to impress the interviewer by answering the question in the very unique and effective manner by considering the position and the requirement of the company..            while answering this question you have to understand the intension of the interviewer and the companies requirement and answer the question in an effective way by highlighting  your qualities suitable for that position Here is the example how to answer this type of questions TRAPS:  Believe it or not, this is a killer question because so many candidates are unprepared for it.  If you stammer or adlib you’ve blown it. BE...

Question 6:   The “Silent Treatment” TRAPS:   Beware – if you are unprepared for this question, you will probably not handle it right and possibly blow the interview.   Thank goodness most interviewers don’t employ it.   It’s normally used by those determined to see how you respond under stress.   Here’s how it works: You answer an interviewer’s question and then, instead of asking another, he just stares at you in a deafening silence. You wait, growing a bit uneasy, and there he sits, silent as Mt. Rushmore, as if he doesn’t believe what you’ve just said, or perhaps making you feel that you’ve unwittingly violated some cardinal rule of interview etiquette. When you get this silent treatment after answering a particularly difficult question , such as “tell me about your weaknesses”, its intimidating effect can be most disquieting, even to polished job hunters. Most unprepared candidates rush in to fill the void of silence, viewing pro...

Question 5  :- Why are you leaving (or did you leave) this position?           TRAPS:   Never badmouth your previous industry, company, board, boss, staff, employees or customers.   This rule is inviolable:   never be negative.   Any mud you hurl will only soil your suit. Especially avoid words like “personality clash”, “didn’t get along”, or others which cast a shadow on your competence, integrity, or temperament. BEST ANSWER: (If you have a job presently) If you’re not yet 100% committed to leaving your present post, don’t be afraid to say so.   Since you have a job, you are in a stronger position than someone who does not.   But don’t be coy either.   State honestly what you’d be hoping to find in a new spot.   Of course, as stated often before, you answer will all the stronger if you have already uncovered what this position is all about and you match your desires to it. (If you do not p...

Question 4     : Tell me about something you did – or failed to do – that you now feel a little ashamed of. TRAPS:   There are some questions your interviewer has no business asking, and this is one.  But while you may feel like answering, “none of your business,” naturally you can’t.  Some interviewers ask this question on the chance you admit to something, but if not, at least they’ll see how you think on your feet. Some unprepared candidates, flustered by this question, unburden themselves of guilt from their personal life or career, perhaps expressing regrets regarding a parent, spouse, child, etc.  All such answers can be disastrous. BEST ANSWER:  As with faults and weaknesses, never confess a regret.  But don’t seem as if you’re stonewalling either. Best strategy:   Say you harbor no regrets, then add a principle or habit you practice regularly for healthy human relations. Example:   Pause for reflection, as if the ques...
