The interview has 4 rounds, 3 technical and 1 hr


Round 3(Technical)

They started with normal introduction like tell me about your self ..

1. He started with question write all concept of oops then explain last 3 with proper defination and real time example ,he also asked where should use
these concept what are the situation where we use these concept .. like why using inheritance why not other concept ,
what difference come if i use other concept of oops rather then you are using...

2. Then he asked about my project.

3. After that he asked some simple question on project.

6. Asked question given an array having some values you can jump from any place equal to the given value at that index asked to find minimum jump
require to reach end.... then he asked for logic to traversing path that followed for reaching end with minimum jump.

*then he told me to ask any question ??


Round 4(Technical)

7. Asked me to explain my c++ project in detail.. then he asked me to make class diagram ..
then asked question on working of project .. then question on relationship between classes .. why that relationship ?? ..
asked about algorithm i used in project ,how storing data .. some of general question.

8. Asked me to write optimize code for finding longest palindrom substring in given string.. expalain flow of program ...

9. Asked me write code for printing all possible permutation of given string..
..make recursion tree and explain flow of program.


Round 5(Technical)

10. started with how was my previous round .. what they asked
