Instrumentation Laboratory Electrical Engineering interview questions

I applied online. Received an email two days after I applied! It read: "Dear Unavailable Variable, Thank you for your interest in Unavailable Variable. ...." I quickly set up a phone interview/screening time for the next day. "Great you are all set" and was given a name of the interviewer and time. On the day on the phone interview I did not receive any call at the scheduled time. A few hours after I emailed asking if there was an issue and there was no response. After a few days I sent follow up email and got a response from the same Talent Acquisitions Specialist five minutes later apologizing for the a scheduling error and that they have moved on with another client. Very unprofessional and a waste of my time. I wish the candidates moving forward good luck and hope the company treats them better.
