Round: HR Interview
Experience: Family Background
Why Freescale


Skills: Static Timing Analysis (STA), Memory, CMOS Circuits, Microprocessor, Digital Circuits
College Name: BIT Mesra
Motivation: I had interest in core electronics

Round: Test
Experience: Written test for a duration of 1.5 hours
Test was based on VLSI design

Round: Interview
Experience: Technical and HR round are held together
Digital VLSI - Verilog skills, state machines, setup and hold time issues were tested

General Tips: Some questions in the test are repeated, so it might help to talk to a few people in advance
Questions are mainly related to VLSI mainly-Digital IC design, analog circuits
Skills: Verilog Skills, State Machines, Setup and Hold Times issues
College Name: IIT MADRAS

Round: Resume Shortlist
Experience: Resume is not given any due importance in selection for further rounds . But honesty is very important as it counts once you are selected for HR round .
Tips: Try to be one hundred percent honest . And put your projects and course work in the beginning. They don't care your POR s and extra curricular activities.

Round: Test
Experience: Hardware - Questions are mainly from ELECTRICAL CIRCUITS (RLC ckts) , Analog ckts. Amplifiers , Opamps , digital system design . Aptitude section is very easy . Hardware section is tough .I felt Signal processing was easier , indeed I got selected for that profile .
Tips: Prepare thoroughly these courses :- EMC , DIGITAL SYSTEMS, NETWORKS AND SYSTEMS,ANALOG & DIGITAL SIGNAL PROCESSING , ANALOG CKTS COURSES .THAT SHOULD BE ENOUGH .
Duration: 90 - Signal Processing minutes
Total Questions: 120 - Hardware and aptitude

Round: Group Discussion
Experience: No
Tips: No

Duration: 2
College Name: IIT Madras

Round: Test
Experience: Test was subjective and questions were asked from basic analog, digital design, VHDL and VLSI circuits.

Round: Technical Interview
Experience: Had 3 technical interviews each around 25 minutes. They asked me about my summer internship and
questions from microcontroller architecture and its interfacing. Then they asked me the questions
from those problems which I didn't attempt in the written test.
Tips: For electrical students, it might be a bit challenging. I took an elective on Microcontroller in 7th sem which
helped me a lot during the interview. You might want to brush up your concepts of 8085, digital, OPAMPs
and analog

Round: HR Interview
Experience: My family background and my future goals were asked. They asked me about
my internship project and wanted to know what I learnt during the internship. Then I asked a few questions
from them about the company work culture and growth opportunities
