Answer Example:
“SMPS stands for Switched Mode Power Supply. Its role is to consistently deliver power to the various components within a piece of hardware. Fluctuations in power are one of the key reasons hardware fails. SMPS devices modulate the power to ensure it is consistent and appropriate for each of the electronic components.”
2. How do you help the people on your development team get better at what they do?
Answer Example:
“Part of my annual plan is a team development strategy. I set training and development objectives for each member and detail the courses or training they need to take to achieve these. In addition to this formal training, I also look for ad hoc opportunities to improve the skill sets of my team. An example of this is assigning them tasks that will stretch them and require them to learn new methodologies for software development. I will also partner a junior member of the team with someone more senior who can mentor them. This benefits the junior member because they acquire new development skills and the senior member who learns mentoring and leadership skills. My goal is to promote two of my team into senior hardware engineering positions each year.”
3. What types of professionals do you reach out to when you encounter a problem on a project that you can’t solve yourself?
Answer Example:
“Even though I am well qualified to work on the projects I am assigned, I recognize my limitations. I am more than willing to reach out to other professionals when I need assistance. Individuals I usually contact include the other members of my team, my management, professionals from other organizations within the company such as software and electrical engineers, the vendor teams I work with, my pool of consultants, and subject matter experts from around the globe. I have developed a very reliable portfolio of resources I can use whenever I encounter a problem I can’t solve myself.”
4. Describe the steps you take when creating a hardware development project plan.
Answer Example:
“When creating a hardware development project plan, the first thing I do is ensure that I completely understand the objective of the project. I then create a list of the resources required, including personnel and technology. Next, I develop an outline of the steps required to complete the project. Once I have this, I review the individual steps and provide additional details regarding the timeline, budget, resources, and other dependencies. When the plan draft is completed, I publish it to my team and other project stakeholders for their review and input. Their feedback is consolidated into the final plan.”
5. How do you manage your and your team’s time during an engineering project with tight deadlines?
Answer Example:
“The ability to consistently deliver projects on time and under budget is something that I’m known for. I accomplish this by first understanding the task and setting reasonable expectations for completion of it. Before commencing with a project, I break it down into individual tasks which need to be accomplished in a specific order and on a specific schedule. I then take responsibility for accomplishing this task or delegating it to somebody with the needed skill set. Finally, I regularly assess the team’s progress against the schedule and make adjustments to complete the project on time and under budget. Tools I use to manage this old process include charts and spreadsheets.”
6. Please discuss pre-layout signal integrity and why this is important when designing a piece of electronic hardware.
Answer Example:
“Pre-layout signal integrity simulation is a process that quickly enables me to confirm that my design meets specifications. It also identifies any limitations within a circuit and allows me to address them before finalizing the design. Even though signal integrity is less of an issue since we have moved from wires to printed circuits and microchips, it can still impact the performance of a piece of equipment and therefore needs to be verified.”
7. Can you describe the type of circuit illustrated by this drawing?
Answer Example:
“The circuit in this diagram appears to be a layout for the control panel and a piece of network hardware. The presence of switches indicates this, as do the LED sockets and other components which enable users to interact with the equipment. It also contains some components that I would include in this type of circuit, including resistors, capacitors, and various microchips. I would assume that each of these is customized to optimize the function of the device.”
8. How can a circuit store an electric charge?
Answer Example:
“A circuit stores an electrical charge using capacitors. Capacitors come in several different ratings and can store electrical charges for designated periods. The storage mechanism within the capacitor is similar to that of a battery, except capacitors use electrostatic fields between their conductors instead of chemicals. When another device activates a capacitor, it releases the energy into the circuit.”
9. What is a breadboard, and how is it used to develop hardware?
Answer Example:
“A breadboard is a practice circuit board used for experimenting with an electronic hardware design or circuit. It is called a breadboard because it is full of holes in which components can be inserted and connected, similar to a piece of bread. I often use a breadboard to test my designs or verify that the design components will work together. It can also help me visualize my circuit layouts which may be too small to see on a traditional printed circuit board or within a chip,”
10. What does SNR stand for, how does it impact an electronic device, and how can it be mitigated?
Answer Example:
“SNR stands for signal-to-noise ratio. It can impact a hardware design by creating interference and unwanted signals that alter the device’s functions or cause other issues. SNR can be addressed by using quality components, making sure all the connections are tight, placing specific components further away from each other, and using components such as amplifiers and other devices to reduce the noise emitted by an electronic device.”
11. How is emulation used in the hardware design and development process?
Answer Example:
“Often, during the design process, one or more components need to function like others within the piece of hardware. This is known as emulation. Replicating the function of the component within the hardware ensures the consistency of the hardware and its performance and reduces the design and development time. Emulation can occur with a device or across several devices.”
12. How are the processes of soldering and de-soldering in the hardware design process?
Answer Example:
“The hardware design process consists of several distinct steps. It starts with conceptualization and includes project planning, design, prototyping, testing, documentation, and release. Senior hardware engineers need to be familiar with each step and discuss what occurs during each process. This will verify that you have experience with the entire hardware design process and the skills needed to perform this job.”
13. No matter how well they’re designed, some pieces of hardware or equipment either never made it to market or quickly became obsolete. Can you discuss why this occurs?
Answer Example:
“Although it rarely occurs, there have been times when my designs either have never made it to market or have quickly failed once put into production. This has never occurred because of the quality of the design or functionality of the piece of hardware. It is often a result of changes in the marketplace or other external factors over which I have little influence. These include delays in bringing the product to market, failed marketing strategies, evolving requirements, incorrect data, or the appearance of new technologies.”
14. One of the design cost components of a piece of hardware is NRE. Can you define this and discuss how it impacts a design project?
Answer Example:
“NRE stands for nonrecurring engineering costs. These are one-time costs associated with the design of a piece of hardware or equipment. They may be in the form of a unique tool, software program, test jig, or other resources needed specifically for a project. They differ from recurring costs such as personnel, facilities, standard equipment, and IT resources shared and used by several different projects.”
15. While the functionality of a piece of hardware is important, companies use other criteria when deciding whether to develop a piece of equipment. Can you discuss some of these?
Answer Example:
“While my primary design criteria when working on a new piece of hardware are performance and functionality, I recognize that other criteria will be used to evaluate my design and determine if the hardware will be manufactured. I keep these in mind when going through the process of designing a new piece
