XOR Gate using 2:1 MUX
Tips: Prepare Digital electronics and Microprocessors very well.Sta is very important.Panel will go deep into the topics to check ur technical knowledge.
TIPS: Be confident and your opinion should be strong.Stand by what you say.Do not get confused.And when panel asks to solve any digital circuits, speak loud what is in your mind and what approach you are using.Be honest.

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: 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
