Relias Content Writer interview questions

Applied online and the next day I had a recruiter schedule me for a phone interview. Went through that and was asked to do an online personality test, and was explicitly told to "be honest because they ask the same questions in different ways". Okay. Got it. I was honest al the way through because in reality, if my answers to that are off-putting, then please do not engage me further! I was also asked to produce a writing sample based on their prompt. Got pushed through to the next interview within a day or two since speaking to the recruiter, and all seemed to be going great. Lots of good feedback, and they seemed excited about me and told me about next steps. After that... crickets. I was completely ghosted by my recruiter despite reaching out multiple times. Big red flag, especially since I handed over my intellectual property (which they seemed to love) and couldn't even get an email? Yikes.
