Deliverect Customer Support interview questions

I received an email from HR asking to send her some times and days that I would be available to have a chat. I sent her a pretty wide-open block of times and received no response. I sent a follow-up email asking if she received my email and she apologized for not responding sooner with another request to use Calendly to book a time. I promptly booked a time and then she ghosted me. Terrible recruiting, terrible manners and as a result, I will probably not consider working for this company.
