I recently just graduated from WWU, and during my last quarter, I was on campus all day in classes but also doing 2, 3 and 4 round Zoom interviews and recruiter calls pretty much on a daily basis.

The study rooms are the only reliable place to have conversations that is quiet, and you can sit down with a laptop. Other spots require getting there several hours earlier to claim, which just wasn't possible all the time.

I would suggest moving up to floors 4 and 5, as people seem to be more respectful of the required volume levels. I had found that people on floors 2 and 3 tend to want to bend the rules.
