I applied through other source. The process took 4 weeks. I interviewed at PerkinElmer (Waltham, MA) in Nov 2017
Interview
Had a couple of phone screens, then I was asked to come in for a face to face interview. The interview lasted for about 3.5 hours and I met with the hiring managers and the other EAs. I never heard anything back, and a few days later I saw the job posted again on Indeed and LinkedIn.
