Four stage interview process. 1. Simple HR phone call screening where they ask nothing serious. 2. They make you take a silly online aptitude test (word puzzles and behavioral questions) which no one ever mentions to you again. 3. An hour-long video call with the hiring manager and a few others where they ask you about your technical background and experience in some detail. 4. They fly you in on-site where you give a technical presentation on your previous work (Ph.D. thesis work in my case) and you have an hour-long technical meeting with the scientific team, and another hour long meeting with the leadership and HR. Unlike other companies, the onsite one with Honeywell was pretty fast, no lunch/meal breaks, no one-on-one time with anyone. Just in and out within a few hours. I got an offer within a week of the final on-site interview.

2 steps 1. Call with hiring manager 2. Onsite tech talk, followed by 1-1 interviews with scientists, managers, and HR. Was led to a room and stayed in the room the entire interview. No lab tours because of security clearance.
