Very good interview process. Spoke with hiring managers, followed by HR. You then get an HR hiring rep assigned to you who assists you through the process. After a background and drug test you are good to go.

Found opening on LinkedIn and then applied via Johnson Controls' website. Regional sales manager called a week or two after posting the application, and asked to set up an interview. I interviewed with regional sales manager and branch manager. Interview was fairly loose; there was no strict regimen for questioning followed. Questions like: Why this position? Why Johnson Controls? What are the components of an HVAC system? What project are you most proud of? Etc. I did my research on the company's product offerings via their website. I read A LOT about the company before the interview to prepare. Received a phone call 1 week later, asking to come in for another interview, which was scheduled 1 week after the call. Second interview was with branch manager, HR rep, and a former salesman turned HVAC technician. Interview was similar to first one. No barrage of questions or "tricky" questions. After second interview, took 3-4 weeks for a job offer. Process was PAINFULLY slow and required several approvals from management. From first call to job offer was probably 7 weeks. Then had to complete the HireRight background check and LabCorp drug screening, which took about 2 weeks. So, first interview to start date was 2.5 months. Incredibly long hiring process, IMO.
