Assisting Hands interview questions

I got a call for a phone screen. The same day an interview via video was set up for the potomac location only for them to cancel the interview three minutes before the scheduled start. This role was perfect for me. Its unfortunate they showed a total disregard for my time, effort and wellbeing by canceling the interview three minutes prior. I sent an email to follow up and it wss disregarded. Absolutely the worst interview experience ever.
