Second Round: interview

In the 2nd round,Hp employees( 2 or 3) will be interviewing us.The Q asked will vary form person to person.

They asked abt my latest projects first.They concentrated less on my academic proj.So plz prepare well abt the latest proj u did.

And then they asked fully in C,C++ like what is the diff b/w const char * and char const *.What is friend fns,virtual destructors,virtual constructors,How will the compiler intrepret when a virtual class is declared and other basic stuff like calloc,malloc.

In java what is the default exception,Is there any priority for the exceptions,finally,heap concepts etc.

They havent asked any Q in N/wing and OS.

This is the stuff which i faced in my interview.Iam agian telling u...This varies from person to person.

But any way all the best for all u guys who got selected for the next round.Its very easy.Dont be in a hurry.Take ur own time.Another advice,If u don\'t know the answer for any Q they asked,be frank.Dont try to bluff it becoz the next Q will depend upon the Q u answer previously.

The interview pattern will be as:

1. Tell abt your self.
2. They will ask for the subjects in which we are strong ( Here they will consider the ranking that we written during written examination & marks we got in written exam)
3. Mostly the interview time will be 45 minutes around (for only people there is about 1.5 hr)
4. HR questions may include here
5. Good thing is They r friendly and cooperative so confidence place role.  If u don\'t know the answer better not to answer than to tell some bad stuff. For me 2 people interviewd. As I told them that I am strong in C they told me to write some programs like double linked list, singly linked list(adding node at last), macros, const *,char *,pointer arrays.

The main question that they asked was how can u compile or execute \'c\' program without editor. (Using TCC utility)

coming 2 cpp only 1 question i.e what is polymorphism.

Java they asked me about protocol used in JSP, which layer does it belongs to, main differences between _Javascript ,java and JSP.

During personal introduction try to excell your capabilities by giving examples like as fast learner, hard worker like..!

If u have any achievements & awards try 2 put them all during personal INtroduction.

The interviewers are very co-operative and highly friendly (so confidence plays vital role)
