Was messaged by a recruiter on LinkedIn. When the recruiter asked me about my background he immediately acted like I didn't have the experience he was looking for, which was odd because I assume he looked at my Linkedin profile. He then described the role and asked me a couple fairly easy questions related to application security. He ended saying he'd send me material to help me prep for the interview and he then we'd schedule the interview however he never did. I followed up about a week later and still no response.
