Application
I applied online. I interviewed at Thermo Fisher Scientific (Middleton, WI) in Feb 2026
Interview
Preliminary screening questions ("What is the minimum salary you are willing to consider?" "How did you hear about this position?") followed by a 10-15 minute phone screen with HR. I was briefly asked about my resume and given some general information about the company. The actual interview was an hour long, the first half with a group leader in molecular bio and the second half with a group leader in analytical chemistry. No other staff were present. The interviewers were polite and friendly, but the questions were pretty tough and I honestly was surprised that I got an offer. The official offer came about a week after interviewing but they said it could take as long as two weeks.
