Ingenero interview questions

I went through two rounds of interview, both went positive. They asked basic questions on NPSHA, PFD, PID, BFD, Distillation, PSV and Control Valves. Initially there was an aptitude test kind of thing for technical and verbal competency.

The first step of the process is a personality test which is conducted by the HR. Once you clear two of these tests, it's time for your personal interview. The interviewer asks you a bunch of questions. The interview goes on for about 30 mins.
