    • Question 5: Questions on setup and hold time again. Setup/hold questions in a circuit with multi cycle clockpath. Which violation is more severe?
    • Question 6: Draw log(Id) vs Vgs for a MOSFET and explain the curve. Questions on subthreshold slope, howVth varies with length, asked to explain what is DIBL
    • Question 7: Describe the design flow from logic to testing and post silicon validation (after fabrication)
    • Question 8: Tested whether I knew any placement, routing algorithms
    • Question 9: Basic questions on testing - like fault equivalence and dominance
    • Question 10: Simple puzzle: There is a river and four people (A,B,C,D) are on one side. They all have to move toother side in 17 min. There is a boat with a max capacity of 2. Time taken by each people to travelalone is A=1min, B=2min, C=5min, D=10 min. If two people travel together, the time taken by them tocross is max{individual time}. Find how they travelled.
    Interview Experience
    There was no separate HR round. Few common HR questions were asked during the third interview.The interviews were very long and took more than 3 hrs for the entire process.

      Resume Shortlist Technical Interview Case Study Interview
      Round 1

      Resume Shortlist

      Interview 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 2

      Technical Interview

      Interview Questions
        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
        Interview 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 :)
        Round 3

        Case Study Interview

        Interview Questions
        • Question 1: Implement the following code using gates(MUX and multiplier) If(A): F = D*E Else: F = G*H
        • Question 2: Draw State diagram to find a pattern 1011.Important to ask: If overlap is allowed.If there are 1000 states, we represent using 10 bits. If ‘P’ power is consumed when the system moves from State 0 to State 1 (only 1 bit is flipped), argue that power consumed when system moves from State 1024 to State 0 (10 bits get flipped) is more than 10P and where is the extra power getting dissipated.
        • Question 3: Timing analysis of Sequential and combinational logic: Definition of Setup time. How does it affect the system. Find the minimum clock frequency given Tcq, delay of all the gates, Tsu, Thold.
        • Question 4: Due to some other type of fabrication, if clock frequency happened to be more than whatit is supposed to be(the one calculated above), how do you handle that situation?

            My suggestion as a senior is be prepared for basics with in depth understanding and don't expect a question which u have seen before. But the fun is if your basic is strong, u can solve very easily.
