Fluor interview questions

After applying to the company job portal, I was asked to come for Face to Face Interview with the recruiting manager followed by HR Personnel and then after a few weeks i was informed that i was selected for so and so position and should be report to work at a particular date

The interview was pretty lengthy and I was asked everything apparently covered in a mechanical engineering coursework. There was a panel of 2 people, one from the static department and one from HVAC. Before that, there was a test covering MCQs from Mech Engineering and Aptitude. They kind of bulk hired trainees.
