Notified by email that they wanted to set up a phone interview. I focused on the job qualifications structural boundary condition definition, first order calculations, heat sink knowledge and calculations.The questions they asked were you know it or you do not, ie basic heat transfer equations, property of materials, statics, dynamics, etc.

Campus interview was conducted for us for the post of internship in thermal engineering.But no PPO was offered afterwards as their were no clause so if your college has a policy of allowing to sit for FTE then that's a good option otherwise think wisely
