Slack interview questions

Applied online. A couple weeks later a recruiter reached out via email to set up phone screening. Next was a 30 min phone interview with the hiring manager. She showed up over 10+ minutes late and seemed rushed & uninterested the entire time. Questions were generic and read straight from a list (not necessary bad in itself - that does standardize interviews). But things got worse when she abruptly ended the call early to, in her words, get ready for her next meeting. Didn't hear anything from Slack for a couple weeks so I followed up with the recruiter, but heard nothing back. Ghosted. Even an automatically generated 'Thanks but no thanks' email would have been appreciated. I love the platform so I was excited about the opportunity, but now my perception of Slack as a company has changed.
