3 stage process. First with Hiring manager, then with another manager and finally with HR. The last stage was to discuss salary. I declined unfortunately as I had another offer

I applied through the website and a week later I received a contact from a recruiter by email for an interview. I dedicated a lot to learning everything about the company, about the vacancy, and aligning my experience with it. In the interview, the recruiter says that the role required experience with a particular tool, but the job description only mentioned that having experience with this tool would be a PLUS. It was clearly a typo as I didn't have the required experience and wouldn't apply if it wasn't just an extra skill. The recruiter said that it was not a typo and from that moment on the interview moved to the end. Hours after the interview the job description page was updated to the part where it said it was Plus for MUST HAVE. A day later I received a denial of a "no-reply" email, where I couldn't even defend myself or suggest anything. Really disappointing to prepare for an interview and, through internal company error, not be considered for the position -- as I had all the other qualifications and experience.
