Software Guidance & Assistance interview questions

Ghosted by recruiter. Recruiter messages me via LinkedIn. We schedule an interview time for them to call me. The Recruiter did not call me. I waited for 20 minutes. I messaged the recruiter back on LinkedIn. To discover if they need to reschedule our call. It's been a week and the recruiter has not returned the message. Ghosting is Weak. It shows a weak HR department and a weak company.
