Convergent Science CFD Support Engineer interview questions

Applied through email from CFDonline. Received a phone interview(~1hr15min) several weeks later. After that, they called me for an on-site interview, the process was almost 6 hrs long. Very technical interviews. You should be able to justify everything on your resume. Know in-depth about turbulence, fluid mechanics and fundamentals of CFD. Combustion is optional. You also need to give a presentation during on-site interview.
