I was emailed a request for an interview I wasn't aware I had to call them when I rescheduled I couldn't get through using the Uber conference app they choose I notified the HR associate 10 minutes before the scheduled call of this issue and they claimed they hired someone else. This all gave me the impression that it was an unvitation to interview as I have never had a company have me call them for a screening and once notified that the app THEY choose, instead of just giving me a simple phone number, was failing and they ignored the issue totally maybe its a good thing since the company is apparently unorganized and lack empathy.
