Interview Preparation Tips
Round: Test
Experience: There were Separate Question papers for cse and ece.
For CSE it was a simple 45 minutes test which comprised of all technical questions. In short, question paper mainly consisted of C, Data Structures, Operating systems and Networking questions. They asked Questions from C(10), Data Structures(5), operating systems(5), networking(3), communication systems(2). Questions were simple and basic. very few of them needed deep understanding of the subject. They asked only basics of operating systems and In networking they asked mainly IP Addressing and subnets.
Tips: For CSE guys ,just be thorough with C ,basic data structures, concepts in operating systems and networking.
Duration: 45 minutes
Round: Technical Interview
Experience: There were two rounds of technical interviews.
Tips: I proposed efficient algorithms and data structures that impressed them a lot. Their first question was 'what is symbolink link'? i did not have any idea of it. i just said sorry i don't know.Then he asked me a lot of networking questions and i answered them all. He was very much interested in my wireless networking project and asked many questions on them. I answered almost all the questions and fully explained all my projects
Round: HR Interview
Tips: In HR a big NOOOOOOO for GRE did all for me.
General Tips: Cover all the basics of operating systems and networking. Be thorough with C and data structures. solve as many C and data structures questions as you can. Be confident and clear in your answers. Be honest at the interview. If you have no idea of a question tell them straightaway that you don't know. Don't try to cheat them. Say NO to GRE or MBA with proper reasons. Don't give reasons like you can't afford or anything like that. Have deep understanding of your projects. Try to do any wireless networking project at any reputed college if you can. That will help you a lot.
Hope for the best. it all depends on your preparations and a bit on luck.
Best of Luck...

Minutes Technical : 10 Minutes
Total 40 questions
aptitude: 7-8 questions and remaining os, networking, c basics questions.
Duration: 60 minutes
Total Questions: 40
Round: Technical Interview
Experience: First Technical Interview - cdma, gsm technology>>osi model>>explain all layer's functionalities in osi model >>tcp/ip protocol>>deadlock>>semaphores kernel implementation>>problems on synchronization (using semaphores, mesg q's)>>simple questions on linked list>>questions on c lang,problem using bitwise operators next--about project>>what is operating system,kernel>>explain operating system architecture>>process address space,proc,uarea,kernel stack>>networks,data link layer, udp,why u need it & its app>> general problem solving (how many zero's 100!)
Tips: Interview was not so difficult all questions concentrate only on basic concepts,not much on algorithms and problem solving.
Round: HR Interview
Experience: tell about your self>>why do you like qualcomm>>what preparation have you done for this interview(mentally)>>what do you like in my presentation
Tips: HR was rude.
General Tips: Be good at basics, do good project and take it seriously. Beside your os-galvin and network-forzon/tananbum try to read os-Design of operating systems(batch), networks - Internetworking with TCP/IP(dougles E.comer) - vol 1 and other vol for programming ,this very good book to get the internal concepts.

4 Interview Rounds
Interview Preparation Tips
Round: Test
Experience: The aptitude test paper was different for ece and cse.
The ece paper consisted of:1) dspFIR and IIR filter, condition for stability and causality of these filters, finding the magnitude response of these filters, the filter coefficients are given, phase delay and group delay of these filters, modulation techniques(like which of the following modulation takes the minimum bandwidth).2)software (c language)The C section had very basic questions on logical operators, bitwise operators, two for loops were given and was asked to compare their complexity, output and error in the program were also asked.3)very few quantitative questions.
The quantitative questions were from time and distance, work done( practice R.S.Agarwal before the exams). the most important thing was accuracy and speed. you should be better than others.
Duration: 45 minutes
Round: Technical Interview
Experience: I had my software interview (C language, OS ,ds) first. the questions asked in the software interview were from the following topics : virtual functions, virtual memory concept,paging concept, segmentation. oops concepts like: inheritance, polymorphism, operator overloading. In the end I was asked to write code to reverse a string and use the concept of dynamic allocation in that. I was not fully satisfied with my software interview, but i answered good amount of questions.
In the DSP interview questions were:
1) how will you generate rectangular wave. I gave them 2 solutions: a) using schmitt trigger circuit. b) by interfacing a DAC with microprocessor and using software delays of appropriate time period.
2) describe the nyquist rate condition and condition for no aliasing to take place.
3) write the expression for reconstruction of a sampled signal.
4)when to use IIR and FIR filters.
5) what are the advantages and disadvantage of IIR and FIR filters.
6)what is linear phase in FIR filters.
7) they asked me about the workshop in IIT,madras on BLACKFINN processors.
8) write the architecture of BLACKFINN processors. I did very well in the DSP section. Infact, I answered all the questions. After the DSP interview, i had full confidence of getting through.
Round: HR Interview
Experience: The HR was very important, because even a very small mistake can send you out of the race for job.the questions asked to me were:
1) why do you want to join QUALCOMM.
2)Why don't you go for higher studies.
3) where do you see yourself after three years.
4) do you have any problem, if posting is given at hyderabad.
5) would you like to work in the software section in QUALCOMM.
6)what did you like in my presentation. Then he explained me all about the companies, the performance based promotion policies and about the work culture.
General Tips: The aptitude paper was not that difficult. speed and accuracy were important. the panel members were very polite and encouraging.The time for which the each interview went was around 15-20 minutes, you have to make sure to impress them in that short time. It was great to give your best throughout the day and get selected in the end. I thank god,my parents and all of u for all the support.
Try to practice aptitude questions at least 2 months before the placements start. be thorough with C,OOPS concepts. Basic knowledge of DS and OS are also very useful. try to do a good project and training. once you enter the interview room, everything is useful. don't say you are going for higher studies. have faith in god, your well wishers and above all in yourself. that's all. see you all in QUALCOMM. ALL THE BEST !

4 Interview Rounds
Interview Preparation Tips
Round: Test
Experience: Only one technical aptitude was conducted. There were 30 questions in it in which half of them were related to dsp and the other half were related to C programming. Based on the test 8 were shortlisted from aptitude test for the interview from ECE.
Duration: 40 minutes
Total Questions: 30
Round: Technical Interview
Experience: There were 2 rounds of technical interview. In the first one I was asked questions related to DSP mostly. They even checked my concepts in Microprocessors and C/C++. It lasted for half an hour nearly. But in the second round I was asked questions in my favourite domain which is communications.
Round: HR Interview
Experience: My HR interview lasted for just 15 mins. The first question asked was which domain I would like to work and why especially in qualcomm. I was then asked to clarify the doubts about qualcomm(incase any) which i would like to clarify from the HR team and then I had a discussion for a couple of mins regarding the company.
General Tips: As this was the first core company for ECE I was a bit nervous but the panel members were very cool and very informal and made me feel comfortable during the interview. They were infact helping me out in giving answers. My second interview lasted nearly for an hour and I couldnt even notice the time, It was more or less like a small technical discussion I had with one of the panel members.
Just be confident about what you know and it is the way you present yourself which makes a difference between you and your fellow mates. Though you might not be thorough in all the subjects you had till now try being perfect in atleast those few subjects in which you are really interested in and in which you want to pursue your career. It is as simple as how planned and confident you are to get something you really want to do.
