Paysafe Project Manager interview questions

I've received an email saying as below: Thank you for applying to the Product Manager position here. We have recently reviewed your application and would like to arrange a phone interview. Please provide a various number of available time slots and dates to ensure we are able to schedule accordingly. Please send an email to (email address of an HR manager) to discuss your availability and confirm the most suitable phone number to reach you on. I have emailed twice to the HR manager I was directed to. Nothing. I even followed up on Linkedin if my emails didn't reach to her. No answer at all again. I can't say whether the interview was difficult or not because it didn't happen. If the position was filled or closed, she should reply to me notifying the situation. It is the *most unprofessional* job-searching experience I have ever experienced.

The processs, it was a ok. Not overly difficult questions. Some behavioral and experience questions. Slow to complete the offer process. But overall good scheduling and follow up from interviewers and HR leads.
