Plant Tour Interview

Hello, I’m a recent ChemE graduate and I have an upcoming plant tour interview at a food manufacturing company for a process engineer entry level position. I haven’t done one before so I was wondering if anyone had any advice that can help me get the job. Some background about my interview process: completed a 30 min phone screen with recruiter, then did a 45 min virtual interview with engineering manager and Technology manager (mostly technical questions), then proceeded with two separate 30 min panel interviews (behavioral/situational questions). The two panels had plant managers, a senior process engineer and the hr manager. I don’t know what to expect for the on-site interview. They only gave me some information about the dress code (jeans, long sleeve, closed toed shoes…) Did they ask you more behavioral questions during the tour? Did they ask mainly technical questions? Thank you!
