Three interviews in total: a short 30 min interview with recruiter, a 30 minute technical interview with the hiring manager, and an onsite interview with the team. The first interview was just a general overview of the process and to provide some additional information on the job role. Second interview was pure technical questions regarding thermodynamics and fluiddynamics, which took me by surprise and felt like a oral pop quiz that I didn't study for. The manager was also very condescending when answers were incorrect. I did not make it to the final interview, but after the second interview I no longer wanted to work for the company.

interview process was long and tedious. started with a recruiter screening, minimal technical questions, then moved to a hiring manager technical interview, following this was a technical presentation to a panel of engineers, i was then brought on site for an interview which included another pannel interview, site walkaround and questioning, then a written multiple choise mechanical assessmnet.
