Interview Questionnaire 

2 Questions

  • Q1. Differences between TDMA,CDMA,WCDMA,OFDM
  • Ans. 

    TDMA, CDMA, WCDMA, and OFDM are different multiple access techniques used in communication systems.

    • TDMA (Time Division Multiple Access) divides the available frequency into time slots.

    • CDMA (Code Division Multiple Access) uses unique codes to differentiate between users.

    • WCDMA (Wideband Code Division Multiple Access) is an advanced version of CDMA.

    • OFDM (Orthogonal Frequency Division Multiplexing) divides the available fr...

  • Answered by AI
  • Q2. How to detect and correct burst errors
  • Ans. 

    Burst errors can be detected and corrected using error detection and correction codes.

    • Use error detection codes like CRC (Cyclic Redundancy Check) to detect burst errors

    • Use error correction codes like Reed-Solomon codes to correct burst errors

    • Re-transmit the data if the error cannot be corrected

    • Implement error detection and correction algorithms in the communication protocol or data storage system

Interview Preparation Tips

Round: Resume Shortlist
Experience: Shortlisted 8 students from resumes for interview.

Parameters for shortlisting (at each stage of process):Varied ResumeAny work done in FGPACG - I had CGPA of 8.66Internship - Was an Intern at QualcommProjects - Digital IC Design-used Standard Cell Design,Wireless-OFDMsynchronization and channel estimation,Automatic speech recognition)

Round: Technical Interview
Experience: Only 1 round of interview was taken.No HR round and only Technical Questions were asked.

Basics in our courses(state diagrams etc.) were tested.Concepts were explained and was asked questions. So, skill ofgrasping and applying were also testedSpeed didn’t matter. How aproblem was approached,thought were testedNo knowledge regarding minors/electives tested.

For Core:No courses/electives looked at(as nothing related to FPGA is taught)Nothing related to BTP/DDP
Tips: Good skills of maths might help.

In the interview, in 2nd question which was mentioned, whether repetition isallowed or not was asked by the candidate.This really mattered as that was theonly thing different he has done from the person who did an intern in FPGA andit might helped in getting selected finally :)
