I was referred by an employee who knew that I had been doing optomechanical engineering but that in my current role I was doing mechanical with a lot of document control.
I spoke with HR, and she was very vague about the title and level. I thought I was applying for a senior optomechanical role; however, she was trying to put me into a different role it seemed.
I had an initial phone screen with a bright but inexperienced engineer, who did not seem to understand the technical aspects related to the job.
After about 6 weeks, another HR represented contacted me to set up an interview with a hiring manager. That manager called me late from his car, and I could barely understand him. He seemed to be interested in hiring me, but he could not understand why I wanted to do opto-mechanical when they had more need in other roles. I pointed out that the whole reason I was interested was this aspect.
