Okay, So i had three calls all together .The first one was from recruiter ,He just asked the basic questions regarding past experience and relocation. Then i had interview with Sr manager .Spoke to her regarding my past experience and skills i have. She was very friendly and Then later spoke to the team manager ,it was just a casual conversation. He wanted to hire me the only reason stopping him was myy visa status. Johnson Controls won't sponsor you. If you're on a F1 visa. Its kinda waste to put your efforts for interview because at the end the only thing matters to them is your Visa status.

The interview was a short in person interview with the engineering director. He asked some basic experience and skill questions and showed me some drawings for past projects. He then went over basic expectations
