Top Electrical Engineering Interview Questions

Top Electrical Engineering Interview Questions

Hardware engineering roles span multiple specialities, but here’s a list of a couple of the verified most asked interview questions by companies such as Apple, NVIDIA, Tesla, and more!

Software Engineering - Many FAANG hardware roles expect you to be proficient at coding. Here are some common questions:

  1. Merge two sorted linked lists

  2. Merge overlapping intervals

  3. Find the maximum sum of a subarray

  4. Search in rotated array

Analog Design - Fundamental analog design along with physics-based questions are common:

  1. What are the differences between MOSFETs and Bi-Polar Junction Transistors?

  2. What are the advantages & disadvantages between a buck converter and a LDO?

  3. Can you draw the block diagram for an inverting operational amplifier and derive the gain equation? - #2 by hardwarefyi

Embedded Software/Systems - For embedded systems, knowing your communication protocols and being familiar with hardware platforms is crucial!

  1. What are the three common communication protocols? How do they (I2C, SPI, UART) work?

  2. MCU vs ASIC vs FPGA

Digital Design - Digital design interviews can vary depending on where you are. For example, Qualcomm is likely to ask leetcode style questions, while Broadcom is likely to ask Verilog:

  1. What is the Nyquist Theorem and how do you define a sufficient sampling rate?

  2. Parallel-in, Serial-out Shift Register

Board Level Design - Knowing PCB fundamentals and design trade-offs is crucial:

  1. PCB layer description - #2 by lsu

  2. Number of PCB layers - #2 by lsu

Signal Processing - Communications and signal processing will grill you on your fundamentals:

  1. What is the Nyquist Theorem and how do you define a sufficient sampling rate?

  2. FIR vs IIR filter
