Round 3

Technical Interview

Interview Questions
  • Question 1: Description of project work and basic questions on DSP and modulation
Interview Experience
The interview starts off with a basic description of your own project work. He asks about what you have done and why you're interested the field. This is followed by 2-3 questions of signal processing/digital modulation. The level of difficulty is reasonably high. But it isn't too tough. He will help guide you if you are stuck somewhere but you are expected to reach a conclusion on your own. The interview will last about an hour if you are doing well. You will be given rough sheets and the interviewer will track your working and gauge you accordingly.
Interview Tips
The interviewer will be interested in the particular technical details of your project work like your bachelor's/dual degree thesis. Be sure to relate as strongly as possible to communication and DSP. While working out the DSP problems, if you get stuck, be sure to ask and clarify the questions. After he has finished, be sure to summarize the problem and confirm what you are expected to find out. It helps a lot if you think out loud as your approach is what is being tested rather than reaching a final answer. Be sure to state the areas you are certain and uncertain about. As much as possible, explain all your points through digrams, equations and illustrations.
Round 4

HR Interview

Interview Questions
  • Question 1: Personal background and experiences
Interview Experience
This is a very informal interview, where the candidate talks in detail about the experiences throughout the undergraduate curriculum. The interviewer may identify certain specific parts of your resume and ask you to elaborate on that. The interview then proceeds to TI: what you find interesting in the company and why you want to join.
Interview Tips
Openness and frankness is what is expected. Do not try to lie or sound ideal. Be yourself honest about your work and views. Read up on TI and their work. Know the major innovations in recent times.

Round 1

Test

Duration
240 Minutes
No. of Questions
80 questions
Test Sections
  • Section 1: Analog
  • Section 2: Digital
  • Section 3: Signal Processing
Interview Experience
The test for Analog and digital was conducted online and Signal processing was offline. Analog tested basic LCR circuits , bode plots and analysis of poles and zeroes. Questions on transistors were also asked. 10/20 would be a good score , give that there is a negative mark of 0.5 for every incorrect answer.

Digital was same format as Analog. It tested knowledge on gates, flip flops and Digital circuits using transistors. The exam was quite challenging.

Signal processing mainly tested DSP (Quiz type questions ) . Quite a lot of questions were based on frequency modulation. A sound knowledge of basics should ensure good marks in test. Marking Scheme +1 for correct and -0.25 for incorrect answer. 20 questions, 90 minutes.

A half an hour aptitude based test which was quite simple.
Interview Tips
Ensure sound knowledge on fundamentals of LCR circuits, bode plots, Op-Amps, pole zero analysis and digital circuits. If possible learn basics on biasing of MOSFETs. For signal processing, revision of course work should be sufficient and lay emphasis on basics of frequency and phase modulation.
Round 2

Technical Interview

Interview Questions
  • Question 1: Explain Fourier Series based on your understanding
  • Question 2: If two sine waves of different frequency are added will resultant wave be periodic. If so what is period.
  • Question 3: What does odd and even harmonics of fourier series signify
  • Question 4: Explain aliasing, nyquist sampling theorem
  • Question 5: If a sine wave is sampled at 1.5 times its original frequency, can the original wave be retained? (Ans: Yes)
Interview Experience
Around 10 to 20 people were selected for technical interview.I was shortlisted for Signal Processing and the questions were quite simple than expected. I was asked to explain concept of Fourier series and based on that questions were asked. In the end I was also tested on DTFT basics and nyquist sampling theorem. It went on for half an hour and ended with a puzzle. No questions on resume was asked.
Interview Tips
Be very confident on the basics. Only your basic understanding will be tested. Also during interview make sure you ask enough questions if you don't understand. The interviewer will guide you properly. Remember your approach and understanding of basics concepts will be mainly tested, not formula or answer to the problem.
Round 3

HR Interview

Interview Questions
  • Question 1: What was the learning outcome from your leadership experience?
  • Question 2: What was the learning outcome from your (particular) project ?
  • Question 3: Are you into electrical related companies or companies which offer leadership profile?
  • Question 4: One word in which your friends would describe you?
  • Question 5: Anything you would like to ask me?
Interview Experience
Around 4 were shortlisted for HR interview. Selection was based on Technical round performance and Resume. I am not sure if technical exam marks were considered for shortlisting.
Questions were asked about my projects and leadership experience. They asked me if I was into core or leadership profile and that if I applied for ITC , P&G etc ( My answer was NO ). My interest in Electrical Engineering should have a positive opinion about me.I had many good projects in my resume. So I was asked about learning outcome of the important project which I worked on and I was able to answer very well. My personality was also tested which I answered quite satisfactorily.

The round ended after I asked the HR about description of kind of projects an intern will be working on and some questions about profile.In general they didn't consider CGPA as a huge factor for hiring interns.
Interview Tips
Honestly answer the questions faced and whenever you get chance demonstrate your interest in working for a core company. Get your resume reviewed by seniors and highlight appropriate Projects, PORs , skills and coursework.Make sure you are prepared to answer questions based on your projects, PORs and about yourself.

Interview Experience
The HR was quite frank and made me feel comfortable. She started a conversation rather than an Q/A session.
Interview Tips
Just be yourself, and talk as much as you can. they try to judge your character within that limited time, and honesty is something given a lot of importance. Try to link questions to your stories - your life incidences which are on the lines of thee questions. Don't sound confused when asked questions such as - Why TI ? or Do you want to pursue research?
Have a clear idea of what you have done in life ( at least for what mentioned in resume) , should imply that you have made a choice, or given decent though for pursuing something. Maintain eye contact, be calm, and confident.
