I applied through a staffing agency. I interviewed at Lunar Energy
Interview
Got reached by team.ai recruiter. Scheduled a call, didn’t show/cancelled the phone screen couple days later. Not sure about the company, if you’re associated with recruiting team that can’t even respect candidates time, no thank you!
I applied through a recruiter. The process took 2 weeks. I interviewed at Lunar Energy
Interview
Two weeks total consisting of 6x 1hr videocalls. I spoke with the recruiter after each call. There were some technical questions on the calls but we mostly talked about my past experiences and motivations.
Interview questions [2]
Question 1
Describe a project you were particularly invested in. What challenges did you face and how did you resolve them?
Describe how you would design a mounting for a resistor. What information do you need to get started? What materials do you use? What manufacturing processes are appropriate?
I applied online. The process took 3 weeks. I interviewed at Lunar Energy in Dec 2021
Interview
My first call with Lunar was with a recruiter, who mostly worked with me to go over job specifications, my interests, and questions I had. He then helped me schedule a "second round interview" with an ME manager (1 hr long). After that went well, the same recruiter worked with me to schedule my "third round interviews" which were three more 1-hour interviews, each with a different senior ME.
Interview questions [7]
Question 1
If you were asked to design an electric toothbrush, a mining truck, and a satellite to be launched in to space, what considerations would you have for each? How would they be similar or different across the three designs?
Draw a stress strain curve (with labeled axes, but no need for numbers/scale) for steel. Point out important features on the curve such as Young's modulus, yield strength, ultimate strength, elastic vs. plastic region, etc. Next, on the same axes (without erasing the steel curve), draw another curve for a harder steel. Then, add a rubber elastomer curve, and finally a glass curve. No need to give actual values for any points on these curves, but the relative properties should be displayed accurately (e.g. rubber has a lower young's modulus than steel, glass has a lower yield/ultimate strength than steel, etc.)
They asked me to describe one of my favorite ME projects I had worked on before. Follow up questions were about what challenges I ran into, what design considerations I looked into, what the results were (and impact for the company), what I enjoyed about the project
Since I was working on my ME Master's thesis at the time, they asked a lot of questions about it-- challenges, relevant ME concepts, design considerations, methods, results so far
I was asked to brainstorm how I could modify a motorcycle engine compartment (with a super simple drawing of the general shape/location on the motorcycle) so that I could cool the engine down more quickly.
They asked me what my hobbies/interests were. Also, if I didn't have to worry about earning money and could do whatever I wanted as a job/hobby for the rest of my life, what would I choose to do (I was prompted with examples like rockstar, professional weightlifter, accountant...)
If I were given an opportunity to take more classes for free in any discipline, what would I want to study? (similar to the last question, this is about interests, not about what you would want to learn to get a more secure/highly paid job, etc.
