Ante Technologies interview questions

Sloppy and lengthy hiring process. I was approached by an external recruiter and had a phone screening for the Junior Market Development Manager role in early February. I was asked why I wanted to leave my job, and I said that, actually, I wasn’t actively looking for jobs because I was happy and had a great relationship with my team and my manager. However, I was open for new opportunities, and I felt that a role in ANTE could be a great next step in my career. After the phone screening, I went through four interviews with ANTE team members, one per week, where I was asked behavioural and role-related questions. They’re all very friendly, and the interviews felt conversational. The red flags I ignored: The first interview was rescheduled once. The second interview was rescheduled twice. I wasn’t invited for an onsite interview, which seemed a bit cold and distant. A month after the beginning of the process, I got a call saying that I was approved. Two weeks later, another call from the external recruiter to say that they wouldn’t be able to hire me because I don’t have Irish or European Citizenship. From ANTE, I got the silent treatment. Did they need 4-5 interviews to reach to this conclusion? I don’t understand why this requirement wasn’t flagged at the very beginning of the hiring process and what is the issue with my stamp 4 as I’m legally allowed to work full-time in Ireland. I don’t need an employment permit or sponsorship. I have worked for two companies under this visa so far. I don’t believe that this is the real reason behind their decision. I was also told that “we are by far not close to perfect and do make mistakes when we are a growth startup”. Being a startup is not an acceptable excuse for being unprofessional. They shouldn't treat people as if they’re disposable. Please advise the HR to be thoughtful when dealing with people’s future. Don’t play with people’s future.
