Lockheed Martin Systems Engineer (New Grad) interview questions

They presented a PowerPoint for a majority of the time explaining all of the different positions at their particular branch. I'm not sure if this is normal for interviews or specifically because this was for new grads. Then they asked STAR questions and asked about things specific to my resume. The one hiring manager was very positive and pleasant to talk to. The other was more negative and had a tone like he didn't even want to be there interviewing someone.
