The first thing they had me do was take a 30 minute pre-screen assessment that covered JavaScript, CSS, and SQL. I didn't do very well on it, but that was mostly me because I was out of practice. They were nice and didn't ghost me after the test. They even sent me a gift card for making the attempt lol. I put easy difficulty because after studying a bit after the test I ran into a lot of what they were testing me on.
