The nearest interview date was about 3-4 weeks after I received the interview date. The recruiter was 15-20 minutes late.

I was led into a room and interviewed by two more senior engineers for an hour-long round of standard interview questions. I had lunch in this room.

Some time later, two different senior engineers came for the design round. One interviewer (Tom A.) did all the talking, while the other interviewer sat in silence and watched. Tom would ask three different questions and then ask me to respond, which I found annoying.

Further, Tom asked very basic questions about every little technical detail and asked me to speak to him as if he didn't have a technical background (e.g., "What data structure would you use? What's a hashmap? What's a bucket? What's a hashcode?"). This made solving the problem slower, but perhaps it was a test of my ability to explain basic concepts effectively.

I wasn't invited to further rounds, which, as I understand it, means I didn't get the job.

What data structure would you use to store a collection of wood boards of a certain length?

Given a desired length of board, how would you select a board or boards to minimize waste?
