Details of types of questions asked in each of the sections:
the aptitude test paper was different for ece and cse. the ece paper consisted of 1)dsp 2)software(c language)
3)very few quantitative questions. 1)dsp questions covered these topics: FIR and IIR filter, condition for stabiltiy
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 bandwidht).
2)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)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.
the ppt started at 12 in the afternoon. It was very important to attend the ppt and be on time.there were 8 panel
members. they were from software and dsp background.This was the best ppt I attended. Everything was so very
clear. they explained everything about the company business and area of work, the work places, work culture,
compensations and benefits.
the ppt was followed up by written test( which had three sections for ece people: 1)dsp 2)software(c language)
3)very few quantitative questions. 8 students from ece and 7 students from cse were shortlisted for the
interview.each of us had three rounds of interview: 1)software, 2)DSP 3) HR. after the interviews were over for cse
and ece , they declared the results.

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.

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.

try to practice aptitude questions atleast 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 wellwishers
and above all in yourself.that's all. see you all in QUALCOMM.ALL THE BEST

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.
