Interview topics/questions which i remember:



1st Interview:



    It covered topics such as extern, static (storage classes) and their examples.

    Detail questions on copy constructors were asked.

    Deep copy, shallow copy (need for explicitly writing copy constructor).

    Operating system concepts such as memory Management and semaphores, critical section.

    Overloading, Overriding(Function and operator both)

    Virtual Functions



2nd Interview:



    Projects discussion,Role in project, Why this project.

    Resume based interview.

    Some more discussions on virtual classes and functions, overloading, overriding, copy constructors.

    Puzzles such as no of 0s in 100!, and water- jug problem.



3rd Interview:



    Merge two double linked list. What will be the difference if they are singly linked list.

    Make a data structure such that it can store an image dynamically.

    Copy fixed no of bytes from source to destination and its test cases( ex: copy(source, destination,bytes) so now command copy(a,a+3,8)  will not give correct results in some cases and copy(a,a-4,8) will not give correct result in some cases , so their solutions)

    Some puzzles like weighing problem..N Balls given all of same weight except one..What is the max value of N so that u can figure out the ball with less weight in 2 rounds or 3 rounds.



4th Interview:



    Some HR questions about family and yourself.

    Detail discussion on virtual functions.

    Optimized fibonacci program.

    Solution for solving problems generated by virtual functions.

    Some good questions on compile time error check, link time error check and run time error check.

    One Image puzzle.



For almost every question/concept, it was asked to write a program for that.
