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: Technical Interview
Experience: I was unable to solve the problem properly but after that he gave me a normal k map to solve.

Round: Technical Interview
Experience: Asked about inverter and delay dependency on temperature and other parameters

Round: Technical Interview
Experience: I managed to answer most of the answer that i did wrong since i had discussed it with my friends after coming from college.

Round: HR Interview
Experience: provided answers that relates company requirements

Round: HR Interview
Experience: Listened carefully about their job description and work environment

College Name: IIT Madras

Round: Test
Duration: 60 minutes

Round: HR Interview
Experience: No prep required for HR round, asked few personal questions (about your background, family, interests etc.)

General Tips: Revise all of your core courses, starting from the basics. Junta usually stumble when asked questions from basic fundaes.
I felt a lot of stress before my first interview, which affected my performance badly. Learn to keep cool, and have confidence on your knowledge.
Skill Tips: You should have ability to analyse a given circuit
Skills: Digital electronics basics,
College Name: IIT MADRAS

Round: Test
Experience: A written test with Core - Essay Type Questions.
Tips: Revise previous core VLSI courses (Digital Circuits, Digital IC Design, Analog Circuits, and Solid State Devices).
Duration: 60 minutes

Round: Interview
Experience: 3 rounds of interviews (15-20 minutes each)Basic digital concepts, ability to analyze a given circuit
Tips: Be thorough with your basic electronics conceptsPerformance in the technical interview counts a lotAnalog devices didn't need any particular course or project, they mainly look for strong basics in digital/analog circuit theory, and ability to analyzeRevise all of your core courses, starting from the basics

Round: Interview
Experience: For the HR round, questions about your background, family, interests etc. are asked

General Tips: Learn to keep cool, even under stress, and have confidence on your knowledge
College Name: IIT Madras

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: Test
Experience: The selection procedure is a test followed by tech interview and an HR interview.
The test had two parts:
 Aptitude (common across all profiles)
 A tech. test (separate for each profile)

Round: Interview
Experience: The tech interview was the important one and the HR interview was just about knowing the student and vice-versa. The tech interview was more concentrated on the basics and more importance was given to the approach of solving the problem rather than solving the problem itself.
No CGPA cutoff.

Round: Interview
Experience: Not very important.

General Tips: The work is well structured and executed. There is a lot of opportunity for more technical learning. Interns are also included into the teams and this helps the intern on knowing about the things going around them and gets an overall view of how things work.
As a whole, the work is very good, and exceeds all the expectations of the students.
