Abbott Associate R&D Engineer interview questions

I had a group interview with 3 senior engineers, they were all unprepared. 2 of them seemed like they did not want to be there at all. The interview was pretty casual, I was mostly asked about what was on my resume and follow up questions such as the challenges I faced while working on my previous projects. Only one of the senior engineer was asking most of the questions. They told me they'll get back to me by the end of the week but they never did. I had to follow up several times and finally got a rejection letter 3 weeks after the interview. It felt like they were all forced to be there, so glad I didn't get an offer. Very awful team!
