BASF Associate Engineer interview questions

Applied online after seeing the job posting on Indeed. Got a phone call and email from HR around 2-3 weeks later where I had to pick between three available dates for in-person interviews. Once I decided, the HR person sent me all relevant documents about the company benefits, information about my interviewers, etc. I interviewed with 6 people: 3 during the first hour and 3 during the second hour, and in total it ran about 2 hours even. Everyone was very nice and welcoming and did a good job with filling me in on the job role. Afterwards, they said they'd let me know within the week but it actually took them about 2-3 weeks to get back to me through HR.
