I always see canonical postings on the stack overflow job board. I thought "hey maybe toss out my line, how bad could it be?"

Well I got past the initial glance at the resume and I received the most insane recruiting email I've ever seen.

After the initial screening, the next step is a written test, an aptitude(iq) test, and a personality test. The written test is anonymized to avoid bias. I'm just going to copy and paste these questions.

"The current stage is your written interview. Please take some time to answer the questions below. We’re looking to get a sense of who you are, what’s important to you, and how you communicate. If you’ve already completed this when applying for another role, please feel free to copy/paste from your previous submission.

The most bizarre thing is they're asking about my grades/ranking in high school. Dude I'm applying for a job, not babby's first internship.

Its no surprise that a company that isn't that big has constant and numerous postings online. They're obviously actively hostile to their applicants and set on wasting as much time as possible.
