Process

I applied online. The process took 2 days.

Charts and metrics:

The 30-minute interview with a Lead Propulsion Engineer started immediately with no behavioral or HR questions.
The first half was a deep dive into my resume projects, specifically focusing on hardware design, manufacturing optimization, material selection, and scaling production.
We discussed how to iteratively improve designs for manufacturability (DFM) and how to troubleshoot failing prototypes.
The second half of the interview was purely "First Principles" technical questions covering statics, structures, and fluid mechanics.

When I got stuck on a question, the interviewer was helpful and guided me to think out loud, encouraging me to use basic physics and energy principles to reason through the problem. At the end, the interviewer took the time to give very detailed, insightful answers to my questions, even going a few minutes over the scheduled time.

Questions

Q: Walk me through the hardware project on your resume. Why did you choose that specific manufacturing method and material?

Q: What is the current failure point or bottleneck on the system you are building? Walk me through your methodology for troubleshooting and iterating on that specific failure.

Q: If you have a cantilever beam attached to a wall and apply a point load at the very end of it, where is the highest stress concentration located?

Q: If you heat and pressurize a cylindrical vessel, where and in what direction is it most likely to crack or fail first?

Q: How does a municipal water pump system work? If the power goes out, how does water still reach a house without active electrical pumping?

Work-life balance, who?

Quality Inspector • Former Employee

Pros: If you need work, the hours are there for you. Each department differs in culture and technical knowledge.

Cons: Often times, a three week surge is truthfully a three month surge.

Great for learning

Senior Test Engineer • Current Employee

Pros: Extreme rate of hands-on learning and seeing things come to fruition, with relatively low politics.

Cons: Long work hours. This is unsustainable if you want to have a life outside work.

Poor Management, Toxic Environment

Mechanical Engineer • Current Employee

Pros: - Given a good team and manager, engineers can succeed and learn a lot. However, these are extremely rare. Most people are fired or leave after <3 years.

Cons: Poor Management - The culture of 'extreme ownership' is weaponized against engineers. Engineering teams are severely understaffed, employee burnout is high, and teams face political arguments and drama with other teams. However, managers blame engineers for all negative outcomes, citing 'extreme ownership'. You are on your own to deal with both technical challenges and managerial challenges. Managers do not help employees solve problems or grow. - There is a double standard of work expectations, and many managers work fewer hours than their employees. Expect to work 12-16 hour days to solve problems and have that work go unappreciated by your manager, who instead will blame you for schedule delays despite working at your physical limit. - VP and executive direction is often misguided, forcing employees to work overtime on tasks not worth doing. For example, I was asked to perform technician duties for weeks as an engineer. - Employees have an average 3-year tenure. You hear about a few employees mysteriously leaving the company every month, and managers and employees pretend to ignore this, and badmouth and gossip about former employees. - There is lots of gossip and backstabbing by teammates and coworkers. Certain teammates do no technical work, but instead weaponize gossip. Managers play favorites.
