Nexus Systems interview questions

I applied online and the company reached out a couple of days later to schedule a call. I promptly emailed back some dates and times for availability. After a couple of days, I didn't hear back so I followed up. They finally wrote back and sent an invite for the following week (a Monday). We did a screen call. At the end, I asked if they had any hesistancy or concerns regarding my background and qualifications. They said "no." Said they'd be in touch with next steps/update. After a full week of waiting, I sent a polite follow-up regarding status. At the time of this posting, there has been no response - I was ghosted. This is rude and unprofessional! This explains/supports the poor scores on this site for employee experience and interviews.
