Interview Preparation Tips
Round: Test
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.
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.
Duration: 240 minutes
Total Questions: 80
Round: Technical 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.
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: HR 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.
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.
General Tips: In general an interest in core profile and the subject would help in cracking Texas Instruments. Focus on the basics for technical test and interview and highlight appropriate point in your resume. Good luck.

4 Interview Rounds
Interview Preparation Tips
Round: Resume Shortlist
Experience: Thanks for letting my resume through even when I submitted it half an hour after the deadline :)
Round: Group Discussion
Experience: Smoothly conducted; no complaints about the organization of the event. (Though Samsung could have done better than keep that "structured GD" which wasn't even a GD :D)
General Tips: Don't sweat it if your resume isn't very illustrious. Some basic projects and maybe experience at some startup would be enough for the resume shortlist (that was all I had, pretty much). The aptitude test has many questions but just try to attempt as many as you can in a relaxed manner. The coding test is peace - review basic algorithms (very basic, not even to graphs/linked lists level). And for the GD just stay calm and even if you can't form a well-rounded speech quickly, just mention your salient features. They will get back to you as they do another round through the people in the room. So just stay calm and think during the GD. You don't need to be a Hitler-level speaker to clear this (believe me, I'm far from it :) ). They take many people so don't worry too much about competition either. All the best :)
Skills: Communication, Aptitude, Basic C/C++
Duration: 2
College Name: IIT Madras
Motivation: I was looking for a CS-based profile but in my heart I preferred one that didn't involve IT (I did apply for those too, for backup). So RnD profiles like Samsung and Adobe fit the bill nicely; I didn't get selected for Adobe though, and people do say that their RnD is better. No way to know, right? :D
Funny Moments: Technically I shouldn't say things about the applicants who took the GD with me (some of them did get through in fact), but I simply have to mention the types of problems and resolutions that were talked about in the "structured GD" - using satellite images to identify and combat poverty, seriously?
And the moderator totally dissed the last guy who talked (out of his turn actually, when everyone was about to leave) - she didn't care about his speech and cut him short saying "let's give you seed money, maybe you'll build a business" !
