A staffing consultant found me on LinkedIn, and arranged an initial phone interview quickly. After several delays in starting the interview, the interviewer finally called me and started asking me questions, something like: "Hello, what is the 1st law of thermodynamics?" (NO brief introduction or position). Some of the questions that I remember are: fundamentals on thermal dynamics (e.g. the first law of thermodynamics), thermodynamics cycle, how compressor, turbine works.
