Mechanical Engineer Interview Experience - Hawthorne, California
Process
I received an email from a sourcer for a phone screening. I was expecting to learn more about the job and then be sent on to a hiring manager for questions. However, the sourcer jumped right into technical questions and was completely unprepared.
It didn't help that I was also in the midst of dealing with a larger presentation for my current job. It was not my most glorious moment.
Questions
What is the relationship between stress and strain?
What are the three types of heat transfer?
How does adding mass to the free end of a beam that is fixed on the other end affect its natural frequency? What about stiffness?
If you have an electrical component in a vacuum with an aluminum rod connected to it and out of the vacuum, and the component was overheating, what would you do to prevent the component from overheating?

In order to be successful, you need to be available/on call 24/7 and work most weekends and holidays. Every year, they are required to fire 10% of the employees, so if you're not a workaholic, you'll eventually get fired.
