Outgive interview questions

I applied for the SEO Specialist role via LinkedIn. One of the talent acquisition specialist scheduled me for an interview with another member of talent acquisition. They let me choose my preferred day and a time. They even asked my alternative online meeting accounts for backup like my own zoom link and Skype account. Come the interview day, I waited for 30 minutes in the zoom meeting room but no one arrived. I checked my Skype account as well and there are no notifications. After the long wait, I decided to leave the zoom room. I sent a follow-up email to both recruiters to tell them that I'd be open if they would like to reschedule but I never heard back from any of them. Basically, I was ghosted and was never provided an explanation. Is this behavior being tolerated by this company? If so, then I'm thankful it stopped right here. I have just saved myself from working with unprofessional people. This is my most disgusting recruitment experience ever!

HR interview will come first and then after that you'll be interviewed by the team's supervisor. After that she'll be introduced as the team leader of the supposed team you will be under if you were to be hired.
