HR screen - peer levels, hiring manager, functional leader. Not too many rounds and all conversational. It was natural and a good and quick process. From initial call to offer did not take too long

I interviewed with this company on two separate occasions, and unfortunately, both experiences were extremely unprofessional. During my first interview process, I met with several individuals across multiple departments and was verbally offered a position. I was told to expect a formal offer, which never materialized. After considerable effort on my part to get clarity, I learned that the company had mistakenly posted the same position across multiple offices but only had the budget to fill one role. Despite this disappointing experience, I remained genuinely interested in the organization and decided to apply again two years later. I was transparent about my previous experience, and the new HR manager, assured me that such a situation would not occur again, going so far as to say she would "personally guarantee" it. After one interview, I was never contacted again. Despite my professional follow-ups via email and phone, I received no response or closure. I was simply ignored. If this is reflective of how the company treats prospective candidates, and thus employees, I would advise others to proceed with caution.
