Johnson Controls interview questions

1st round is the exam on aptitude and technical knowledge.They conducted 2 technical rounds after that manager round and hr. I cleared that interview. After that they sent offer letter to me.

The selection process was of 3 rounds , 2 technical and one HR. The technical round was great, and the interviewer asked good questions with core concepts. The technical questions were not easy to answer. However, I answered all of the questions because I have good knowledge of my engineering field. But for average students, the questions were very difficult to answer. Overall, the interview was great and easy for me.
