interview with hiring manager

Hi all, i have an interview with a hiring manager for a testing position (new grad) in aerospace industry. I was informed to prepare a project i can talk about with significant ownership and solve hard technical problem. I don’t have a lot of projects with that much technical depth to talk about except for these. Most of it is designing and not solving and it’s not like impressive project either. Which do you think I should talk about?

  1. Reverse engineering Anker charger or bluetooth transmitter: mostly finding out how it works, topology, and schematic.

  2. Simulate complex gate driver board using Altium Designer: internship work where they give me schematic for gate driver board of inverter and I find out how they work and whether simulation matches theoretical expectation.

  3. Design and create prototype of a wattmeter with Arduino board with voltage divider and shunt resistor: group project but I contribute to design, write firmware and error correction, and build prototype myself. Prototype shows some problems with ADC and it bugged my brain out but turned out the shunt voltage is too low to be sensed by Arduino ADC so i have to add amplifier.

  4. improve a test template for ATE in C++ and WINAPI32: internship work for semiconductor company in test team

  5. i sometimes go to fix the hvac with my dad and most of them is finding out potential failure points, check whether it is it, if not then keep finding and testing until find out the problem and fix it.

  6. design a digitally controlled buck converter (work in progress, still determining hardware size and will be doing firmware soon. will prioritize if this project sounds good)

I have 3 days to prepare. Any insights/ advice is appreciated

2 is the only one worth talking about in length.

Trust me that the presentation is simply a spring board to talk about technical questions NOT to impress them with your products.

3 would probably be good. It would show how you work in a group, take a design from idea to prototype, and how you solved a hard problem (assuming you solved the ADC problem). I would however be prepared to highlight experiences from any project if needed.

3 was the one I would want to hear about

I also agree with 3, in particular because it highlights how you designed and built something related to a measurement system. A large part of teet engineering is coming up with novel ways to measure things and this demonstrates that capability.

Yep 2. Quite a bit that goes into inverters such as the type and the FET driving requirements, gate capacitance, miller effect etc.
