Interview 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 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?

Round 1

Test

Duration
130 Minutes
Test Sections
  • Section 1: Written Test
Interview Experience
In apti , question asked were based on algo design
1.Print fibonacci series in reverse order upto number N. 2. Swap two integer using pointers. 3. An algo for finding weight to weigh 1-40 kg using min. no. of weights.(1,3,9,27). 4. An algo for finding stuck at '0' in a given ckt. etc there were totally 10 question.In Technical, question was focused on basics of network analysis (RC circuits), question on State machine, priority decoder, NAND-NOR implementation ,Op-Amp circuits, fault detection in a digital circuit, synchronous counter. One question was on current mirror, cmos inverter. there were totally 17 questions.
Round 2

Technical Interview

Interview Experience
In interview, they asked Network analysis, digital and VLSI. In VLSI, they asked about CMOS inverter, layout of inverter, various capacitors in a MOS and their effects. Why CMOS ?In digital, they asked T to D and D to T, fault detection in digital circuit, no. of 3-input Or gate required to make n input OR (n/2 if even or (n-1)/2 if odd).
In NA, they were stick to RC circuits, what u can do with resister, capacitor and both. Analysis of voltage doubler ckt, and they made me solve some RC circuits..They asked of pipelining, its adv. as well as disadvantage .They also asked about programming skill (sorting algo).
Round 3

HR Interview

Interview Questions
  • Question 1: Mine and family details
  • Question 2: Companies attempted till now
  • Question 3: Have u got any job
  • Question 4: About higher studies
  • Question 5: If u don't get job, what u would do
  • Question 6: What do u like about college ( I started appreciating each n everything of college one by one then he ask me what u don't like about college).
General Tips
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.

All the best!!!!!!
