What is the difference between semaphore and mutex ? What is spinlock ? What is thread ? What is paging ? What is virtual memory ? Can we have an infinite amount of virtual memory ?

This followed by detailed discussion of each project and internship.Since my project was in Device to device communication and Qualcomm works in that area the rest of the interview was centered around my project only.

HR:

Why Qualcomm ? What is your M Tech project ?

What are your weaknesses ? Hobbies ? Any higher education plans ? Family background ?

Along with all skill sets they look for good CGPA as well.
