Accepted Offer
Positive Experience
Easy Interview

Application

I applied through college or university. The process took 1 day. I interviewed at IDEA Cellular (Mangalore (India)) in January 2013.

Interview

Hiring process was cool ! ...I got an offer though campus placement. It was a 3 round selection procedure. There was a 1 hour online test involving aptitude questions and technical questions ( tech: all areas related to communication engg were covered). Later there was a group discussion and then the last round was personal interview. In the interview round, questions were all based on modulation techniques, which is better ? QPSK or BPSK -and why ? what is Sampling theorem , what is quantization , what is coherent and non-coherent FSK? Circuit diagram on OPAMP based integrator etc.. Also they asked about major project. I was confident while answering the questions. I hope this thread helps some one looking for jobs related to mobile communications.

    3)Personal Interview(HR + Technical)

    Interview Questions

    • Total 50people appeared for the test.They have shortlisted 17people for GD.After GD, 10people went to the final round. While coming to the final round, I can see its a bit tricky interview because they are lining up questions based on your resume and your answers. For me, interview was taken by vice-president of IDEACellular. One advice is that they dont want to waste their time on persons looking for higherstudies.
      In interview, they started with(in order): Tell me about yourself ,Why do you want to come to IDEA? ,
      Your profile looks good and you are more apt for M.Tech!!!(Dont get stuck at this point and if you got stuck,its checkmate.Just say No and give your answers accordingly).
      They'll scan each and everyline in Resume( so prepare well about your projects and internships).
      Later after 15min, they started asking technical questions. As i choosed my fav. subjects as Logic design and networks,they tested me in that fields.
      What is difference between Latch, Flipflop?
      What are latest modulation Techniques and compare anytwo of them?
      What is Opamp(where and how does amplification comes inside opamp)?
      What is zener diode?
      Where do you want see yourself in 1year after joining in IDEA?(This is unexpected question for me! If it was 5years, i would have given answer well. I told them, I'll grasp all the knowledge of my job and will be in a good team).
      Difference between QPSK, BPSK(comparision) and FM vs AM?

      As my interview is the last one, everyone of panel members(4 senior members) are dozed off.Then they offered me a chance to ask for questions.Interviewers all so professional(vicepresident,Director of HR, Sr. Manager and an assitant).I asked about some doubts on 4G Technology.
      Overall interview happened a timespan of 30-40min.
      ADVICE for juniors:Evaluation is cumulative(test to interview), prepare well on projects.
      Salary offered is Decent salary(5LPA inhand) + many perks (as it is a part of Aditya birla group)
      Moreover NO BOND of joining.
      They selected 5memebers at the end( I was one among them).All the best friends. Dont look at the starting salary,Hike of salary in IDEA is more than anyothers( My current senior in his 4th year who joined as GET has 14LPA now).   Answer Question

First part of the interview was mainly on HR questions like "Tell me about yourself, your hobbies etc". The second part was on technical knowledge. Questions were asked from basics of Analog, communication systems, Antenna, Microprocessor. Questions were tricky and they kept on asking questions one after another before you could finish your answer. Their aim was to test the patience and confidence level of the student.

    Interview

    Overall Four Rounds

    First Round- Online Assessment (Technical + Aptitude Questions)
    Second Round- Group Discussion
    Third Round- Technical Interview
    Final Round- Interview with Network and HR Head (Circle)

    The online assessment was tricky and tough. Group Discussion was moderate. All they were looking was how much your contributed in the discussion and if you displayed team spirit.

    The Technical Interview was not at all standard and relevant to the position. Expect some weird questions.
