I applied through a staffing agency. I interviewed at Charm Sciences in Oct 2025
Interview
Phone screen with HR, on site interview with several people, written quiz on PLC knowledge, hands on PLC programming exercise, plant tour. The quiz was multiple choice with approx 50 questions. I was given approx 30 min. The questions ranged from basic computer skills (definition of RAM) to more PLC specific questions to troubleshooting questions. I must have done ok though because I was invited back.

How do you manage your time when working on multiple projects
I applied online. I interviewed at Charm Sciences (Lawrence, MA)
Interview
Phone screen with recruiter followed by in person interview with supervisor. Phone screen was only a few minutes long. Relatively simple and straightforward. Friendly and conversational chat. They had a lot to say about the company and I came away with a more clear outlook.
Zoom with hiring manager. Good easy conversation. Would have been a 5 round interview session but I did not get called back after 2nd round. No follow up about decision
