I applied online and interviewed at Qualcomm CDMA.

Interview Details – This is a telephone interview. An India guy interviewed me. But I was not used to his accent; eventually I failed. The first part is to demonstrate myself, which is normal; then the interviewer started to ask questions; mostly about C and a little bit about telecommunications field.

Interview Question – Many questions about C. Not to many about telecommunications.
One question:
int *a=10; a++;
string *a='10'; a++;
What's the difference between them? Anyway, pointer problems all over.

Another one:
Explain what you know about an TCP packet; what's the difference between TCP packets and UDP packets?

I applied online and the process took 2 weeks - interviewed at Qualcomm CDMA in October 2012.

Interview Details – A phone interview was set up and questions about my research work was asked. Just couple of questions on static and volatile keywords.

Onsite interview was with 5 teams and all of them were coding questions. standard C questions on linked list, function pointers, priority inversion and so on. One guy asked Math puzzles, I struggled a bit after constant coding. But i picked up towards the end

Interview Question – Math puzzles were simple, but my brain was tuned in complex thinking and switching to simple mode was bit difficult   Answer Question

I applied online and the process took 4 weeks - interviewed at Qualcomm CDMA in October 2012.

Interview Details – I applied online. Got an email to schedule phone interview the very next day. Phone interview was mostly focused on C, OS and Networking. Since I did well on that, I was called onsite after a couple of weeks. Onsite consisted on 5 tech rounds and 1 HR round. Tech rounds are entirely focused on C, OS, problem solving skills and your resume. The interview process was very smooth and candidates were well taken care of. I am waiting to hear back from them.
Tech questions were as follows.

1. Programs for binary search, linked list node deletion, string reversal, calculate no of bits in a number in given base, division of floating point numbers.
2. Difference between macros and functions, why/where to use macros
3. Use of static
4. Scheduling
5. How to prevent deadlocks
6. What data structures is used in routers

Overall, the key is to be thorough with C, OS and memory management

Interview Question – Lunch interview was the toughest. The interviewer went deep into OS and memory management.   Answer Question

Onsite interview was 6 technical interviews. Questions from C, data structures, OS, bit manipulation etc. The whole interview process took an inordinate amount of time and I had to wait nearly a month after the interview to learn the final result.
