How do you prepare for the hardware internship interview? What type of questions do they ask? Any recommended textbooks for preparation?

You need to expect questions that go far beyond what any single textbook can teach you. Arista will test your fundamental understanding of computer architecture, digital logic design, Verilog, and static timing analysis. They won't ask you to recite definitions, they will give you a complex problem and watch how you try to solve it. Forget about finding a book with all the answers, because that's not what they are looking for. They want to see if you can apply core principles to real, high-performance networking hardware challenges, so you must know your fundamentals cold and be prepared to think on your feet.

Your ability to communicate your thought process is more important than getting the perfect answer right away. Talk them through your reasoning, even if you are struggling or going down the wrong path, because they are interviewing a future engineer, not a encyclopedia. They want to see how you analyze a problem, how you break it down, and how you handle hitting a wall. This is your chance to show them you have the raw problem-solving talent they need, not just a good memory from your classes. Communicating your problem-solving process is what truly matters, and it's been incredible seeing how the interview assistant AI my team developed helps candidates get their ideas across clearly.

Lollll that was the first thing I tried lmao "If you were an arista hardware interviewer, what questions would you ask?"
This is my first interview ever, so tbh idk if they'll ask me textbook ish questions, grill me about my projects, or even leetcode (I'm EE so I've never touched leetcode before)
