Both interviews with Recruiter and a technical one were average, but they were late with their own estimated deadlines for providing feedback. The second interview was postponed as well. After they promised to get back with their decision in 3-5 days, the recruiter went MIA, and was not responding to my messages for days. Then replied saying nothing specific like "decided to move on with more experienced candidates". She clarified then that the hiring manager did not mention any critical remarks regarding my candidacy. Should I mention that the vacancy is still open, after a few months since I applied?
