Extremely technical interview, with questions on transistor design and application. Also asked in-depth questions on digital logic design and VLSI. I personally think asking extremely technical questions on the phone is ridiculous, especially if you don't have the question and figures in front of you. If you are an Electrical or Computer Engineering student seeking an internship, make sure you understand ALL of your core-level classes like Electromagnetism, Digital Logics, Electronics, and basic Programming.
