## My Texas Instruments Interview Experience (Internship) Last year, I had the opportunity to interview with Texas Instruments for an internship role. I was selected for technical interviews in both analog and digital domains after passing the initial technical test. The interview process consisted of two rounds. # Technical Rounds: Digital In the digital technical interview, the questions were mostly direct and focused on fundamental concepts. I was asked about flip-flops, muxes, static timing analysis, and binary-to-hex code conversion. The interviewer also inquired about a startup project I had worked on, wanting to understand my contributions and the technologies I used. The questions were mostly from digital design, including logic gates, muxes, and other digital-related logic. # Technical Rounds: Analog The analog interview was quite different, featuring tricky questions about op-amps and analog circuits. These questions required a strong understanding of the subject's basics. The interviewer started with RC circuits and progressively added complexity, such as adding an extra capacitor or providing an initial charge, then asking for analysis after each modification. # Topics Covered & Difficulty The technical interview questions were of medium difficulty and covered a range of topics: * **Digital Design Fundamentals:** Questions on flip-flops, muxes, and logic gates tested my understanding of basic digital building blocks. * **Static Timing Analysis:** This involved understanding timing constraints and how they affect circuit performance. * **Analog Circuit Analysis:** The questions on op-amps and RC circuits required a solid grasp of analog fundamentals. You can find the exact wording of the questions I was asked in the dedicated section below. # Company Culture Overall, the company culture at Texas Instruments seems very positive and supportive. # Advice for Others My advice to others is to focus on the basics of digital systems and have a strong foundation in analog circuits if applying for an analog role. Understanding the fundamentals is key to tackling the more complex problems they might present.

Very friendly interviewers. They focus a lot on your projects. Be thorough with low level details of how you have implemented things in your projects. # Overall Process Since I am from a Computer Science background, they asked question about Computer Organization and Architecture, Memory Models and basic C programming (DSA was also covered in this part). One question was on the difference between pass by value and pass by reference functions. Some more questions were asked about memory safe languages (like Rust) since I had written about them in my Resume. Other than that, they also ask about your interests in related domains, (for example they asked me about Linux Driver Development which I was just getting into).

# My Nvidia Technical Test Experience I recently completed a technical test with Nvidia for an Internship + FTE role. The difficulty was medium, and my application is currently in process. Here's a breakdown of my experience. # The Process The test contained aptitude questions that resembled the logic, problem-solving, and analytical skills needed for JEE mathematics. The questions were designed to assess fundamental abilities crucial for the role. # Topics Covered & Difficulty The test included questions from Digital Systems, with a focus on Static Timing Analysis, Johnson and Ring Counters, and FSMs (Finite State Machines). There was also a significant portion dedicated to Computer Architecture, covering memory depth and other memory-related concepts. One question involved CMOS regions of operation. The C programming section had three questions where I had to analyze code and determine the output, which were relatively simple. # Advice for Others Nvidia covers wide variety of topics inclduing CA and microprocessor & mincontroller , so focus on these area also.
