A recruiter reached out to me regarding a job posting for which I was somewhat qualified. I was very specific about what I knew and didn't know in regard to the job posting with the recruiter, who told me not to worry, stating they rarely found anyone who matched every single requirement.

I had a call with the hiring manager who asked me some very basic questions. I answered all but one, and that was really just because I was given about five seconds to answer. I had the distinct impression the hiring manager had already decided against me even before any questions or comments were made on the call.

A few weeks later, I got feedback that they weren't moving forward with my candidacy based on my lack of knowledge of Java and Python. This is strange because I do have that knowledge, yet neither the recruiter nor the hiring manager asked any questions in regard to those topics.
