Normal 4 round interview process. 30 minutes with HR 1 hours with AR manager 1 hour with hiring manager 45 minutes with COO Interview process was speedy and all happened in one week. They were looking to hire someone asap to replace the current AR manager who they kept stuck in that role. I was able to make it to the reference stage where I provided them multiple references on 5/22. My references were contacted via email and they provided their calendars only to not receive any followup. I also didn't receive follow up for over 2 weeks, even with emails to HR (they were quick to respond going back and forth on references and needing emails though) . On 6/5 they sent a basic rejection email and then HR followed up with another vague email.
