Iron Mountain interview questions

Pretty straightforward. I had a recruiter reached out on LinkedIn. Had an introductory call with them followed by a first round interview with the hiring manager. Both conversations were pleasant and went smoothly, I particularly enjoyed speaking to the HM who was friendly and made the exchange feel very casual and conversational. However communication dropped off after that call. I followed up with the recruiter weekly for about a month. They kept saying there were no updates until about a month later when they responded that all positions had been filled. It felt a little dismissive and unprofressional.
