I applied through university. I interviewed at EthosEnergy (Houston, TX) in Nov 2014
Interview
First round is simple, just behavioral and situational questions. You may get asked a couple technical questions about turbomachinery but that depends on who is interviewing you. 2nd round is in Houston, TX at corporate office and is much more thorough. 3 one on ones, a test, and group events that take a full day.
Interview questions [1]
Question 1
