Slack Enterprise Account Executive interview questions

Applied online and received an email from Recruitment team interested to proceed with the interview. There were 2 links in the email one where I can put in my availability which I did and followed up with an email but I haven't heard back and the other link where you have visibility of their calendar and you can book the interview which I used as well. I have received a confirmation email for the interview time. After spending time doing my research on Slack the recruiter didn't even show up, I sent her an email and never replied. This just says a lot about apathy in this company and not respecting people's time.
