Johnson Controls interview questions

The interview was set up with me and three managers. They basically went over how the internship would work, being 9 weeks in the field and 2 in the office. Then he went through my resume and asked a few questions about my experiences. Pretty relaxed, did not feel too much pressure.

Interview was scheduled through employee referral .Process started with a technical interview focused on micro controller,C and few protocols like I2C,SPI .It was easy.In second round most of the questions were from C and little from previous experience.Final round was HR round which was conducted next day ,usual HR questions were asked in that.
