I had a referral from someone at the company and I was contacted by an internal recruiter who did a video call phone screen interview which went well. Afterwards they scheduled me for an interview with the hiring manager. An hour before my scheduled interview they cancelled and told me it was an emergency. They asked me if I could reschedule for tomorrow and I responded yes, but go no response back. I followed up several times and was told the recruiter who I was working with no longer worked with the company, but they would reschedule me again for next week. However, when I followed up again to reschedule for the next week I got no response back. All around this was an extremely unprofessional experience and reflects very poorly on the company.
