INTERVIEW

Regarding CISCO interviews...... they asked about project and some C and data structures and to some students some basics of networking and OS questions..... There were 3 panels. 2 panels for Software and 1 forhardware. Student has to give only one interview in any panel.There was no separate HR interview.... interview was of generally 25-30 minutes duration. 2/3 persons in an interview panel....Finally from IISc, in Software, they selected 9 people from ComputerScience and in hardware, 3 from CEDT(Electronics Design).



Interview Questions

0. M.E. Project

1. If you are not having a sizeof operator in C, how will you get to knowthe size of an int ?

2. Write a macro to set the nth bit ?

3. Can you use a variable in a file using extern which is defined asboth static and global in base file?

4. When we declare union in C, how is the size of union allocated in thememory?

5. What is the boundary problem in allocation of size of structures?

6. Data Structures:-

a. Write a program to reverse a linked-list.

b. Some trees question...what is balanced binary tree?..etc.. One software panel asked about the courses they had done here in IISc. To some people, they have asked some OS and networking questions like OS Questions:

1. What is the difference between user and kernel space?

2. What is real time OS and how it's different from other OS?3. signal and interrupt handling.



Networking Questions:-

1. Sliding window protocol.

2. TCP And IP differences.
