Straight forward interview process, remote position with a lot of room for growth, three interviews total, all with 2 people each nothing too difficult just prepare too answer position related questions

I was emailed and told to schedule a time through a link for an interview. If there wasn’t anything within the first week then I should let them know. I did, and also scheduled for the following week. Then she said she’s on PTO and I had to reschedule, which I did. When it was time for the interview, she never called me. Through further communication I found out that the job had been given to someone else. The disconnect in conversation and lack of urgency was frustrating
