Slack Customer Experience Agent interview questions

About a month after applying through LinkedIn I received an email from a recruiter, requesting I write up some replies to a few customer/work experience questions. After that step I moved onto scheduling a 30 minute phone interview. The recruiter asked my availability for the next two days (not much advance notice). They had very limited availability themselves and didn't respond to my email until the dates they asked about had already passed by with no response. About 2 weeks later we got the call scheduled and the recruiter did not even call me. The whole experience was very unprofessional and not respectful of my time at all.
