Accent Food Services interview questions

I enjoyed the interview process but then COVID came. They reached out to me again when things started back up again. I appreciate their consistency and am excited about the upcoming opportunity.

Quick phone interview then left in the dark for 2+ weeks. I receive an email saying they would like to schedule an in-person interview but I haven't been responsive for two week.... no call/email or voicemail. I scheduled the interview then got a call the next day to change the date. I arrive in person get a quick 15 minute face to face then leave being told I would hear back by the end of the week. Never heard anything, emailed 2 weeks later asking what happened, no response... very unprofessional.
