1. Can you discuss a time that a team member made a mistake and the steps you took to correct it?
How to Answer
Competent computer hardware engineers know how to recognize and correct mistakes made by themselves or other team members. Recognizes that you may not have the leadership authority to take the initiative to correct somebody else's mistake. You can do this either directly or by collaborating with the person who made the mistake to correct it. The interviewer is interested in your initiative in this area and whether you are willing to take responsibility for other people's mistakes. Make sure your answer addresses not exceeding your authority when correcting someone else's mistake.
Written by William Swansen on September 13th, 2021
Answer Example
"Whenever I recognize that a mistake was made, either by one of the other team members or me, I take steps to correct it. If I made the mistake, it is my responsibility to fix it. If another team member made it, I would consult with them and collaborate to correct the error. An example of this was when one of my team members forgot to design a heat sink for a very high-speed microprocessor that emitted a great deal of heat. Fortunately, I recognized this early in the design process and pointed it out. My teammate appreciated my intervention, and together we modified the design to include the heat sink. Our management team acknowledged how well we worked together on this."

Answer Example
"A microprocessor is an integrated circuit on a chip used in a hardware design. It performs a specific function within the device by executing logical instructions provided by the operating system or other applications. Elements of the microprocessor include logic, arithmetic functions, and control circuitry. An example of a microprocessor is the computer CPU or central processing unit. This is the brain of the computer that uses not only the operating system and application software but also other chips or microprocessors within the system to complete the functions for which it is designed."

29. What are some of the factors that affect the speed of a microprocessor?
How to Answer
This is an example of a follow-up question. It refers to a previous question and answer. Interviewers use follow-up questions to clarify any answer or to explore the topic in more detail. They may also use a follow-up question later in the interview to calibrate your answers and make sure you're consistent. As with any question you are asked during an interview for a computer hardware engineering position, keep your answer brief and to the point.

30. What is a heat sink, and why is it used for?
How to Answer
Computer hardware systems contained hundreds if not thousands of components. As a computer hardware engineer, you need to be familiar with each of these and their function. Interviewers can ask you about any of these during the interview and expect you to know about them. Your experience should allow you to do this easily. However, reviewing the common components of a computer hardware system before the interview will help refresh and prepare you. Practicing questions like this one will also enhance your ability to respond to the interviewer's questions.

Answer Example
"A heat sink is a component within the computer hardware system that helps to dissipate the heat of the component which it is attached to. Typically, this will be a microprocessor that runs at high speeds using lots of electricity and produces much residual heat. Heat sinks are typically metal components designed to direct heat away from the processor. Not having a heat sink would result in the processor failing and the computer shutting down."
