## 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.

# Nvidia Technical Test Experience I recently completed a technical test for Hardware Engineer position at Nvidia. Overall, I would rate the difficulty as medium. My application was for a intern+full-time role, and the result is currently in process. # The Process I was literally shocked when I saw the questions for the first time during the test. There were no multiple-choice questions. Instead, we had to calculate the answers and then write them in the blank spaces provided. This was the first time I had seen an exam pattern like this during a placement exam. It definitely caught me off guard, and I had to adjust my approach on the fly. I was able to solve around half of the questions. The test was quite lengthy, and the questions were challenging. Time management was definitely a key factor. The aptitude questions were tricky but looked easy, requiring careful reading and quick thinking. # Topics Covered & Difficulty The questions covered topics from digital design, microprocessors and microcontrollers (MPMC), and static timing analysis. The digital design questions focused on combinational and sequential logic, while the MPMC questions involved assembly language and memory organization. The static timing analysis questions were particularly challenging, requiring a deep understanding of timing constraints and path analysis. ## You can find the exact wording of the questions I was asked in the dedicated section below. # My Thoughts on the Culture Nvidia's company culture seems excellent. Nvidia is one of the most rapidly growing companies worldwide, and that growth fosters a dynamic and innovative environment. During my interactions with Nvidia's employees, I found them to be driven and enthusiastic about their work. The company seems to encourage creativity and collaboration, which are essential for success in the tech industry. # Advice for Others Based on my experience, I advise others to focus on digital electronics, microprocessors and microcontrollers (MPMC), and static timing analysis. A strong foundation in these areas is essential for success on the technical test. Additionally, practicing similar types of calculation-based questions can help improve your speed and accuracy. Make sure to allocate your time wisely and remain calm under pressure. Don't be afraid to ask for clarification if something is unclear. ### Furthermore, remember that Nvidia values innovation and problem-solving skills, so demonstrating your ability to think critically and approach challenges creatively is crucial.
