Not insight per say, but I can share my personal experience...
I took a a couple years off after receiving my BA. I had applied to four top-tier grad schools (young/naive) during my Senior year and only received one unfunded offer. It was a serious blow to my self-esteem.
As a Plan B, I applied for a prestigious internship which I fortunately received. Afterward, I received a job at a reputable artist’s studio where I have been working for the past couple years. I have tried to remain active in my city’s art scene, have had a few speaking engagements, done some curatorial work, and volunteered a few places.
My post-BA experience turned out to make a world of difference! This application cycle, I have received three funded offers, one rejection (meh), and have one decision still pending. Honestly, staying optimistic was difficult at times, but the time off was worth it.
I know there are great institutions still accepting applications for summer internships. It couldn’t hurt to apply to a few, just in case!
