General Dynamics Mission Systems Engineering Leadership Program interview questions

The interview process took about a moth and a half. I applied online and a few weeks later I got a call for a Zoom 15 minute interview. There we discussed my general interests and how/if I would be a good fit. 2 weeks later, I moved on to the final interviewing stage. It was a 3 hour interview where the first hour was a presentation of what GDMS does, benefits, structure of the program etc. The two remaining hours were slit into two, one hour interviews. The first interview tackled my Leadership and community services experience(i.e evaluated the leadership aspect of the program). The second interview should have evaluated my Engineering expertise, technical problem solving skills and design experience. Instead they spent the entire hour asking me questions like "How many ping pong balls fit on a plane". This really turned off my interest to GDMS and even though I was offered other full time positions I chose not to pursue them.
