I was contacted by email by one of their HR recruiters after submitting a resume and cover letter online. We scheduled a phone interview for a few days later (this was around Labor Day, so there was a holiday to deal with). As I waited for a call , I received an email at about ten minutes after the scheduled time. The HR recruiter wrote he was in a meeting that ran long and asked to reschedule the phone interview for another day. I, of course, said yes and offered up a couple dates and times. I received no response. I emailed again after couple of days after that, for about a week, and I never received a single response. To schedule an interview, cancel, and ignore follow-up emails is one of the most unprofessional things I have seen in an interview process. I honestly cannot imagine how their company is run if this is how their HR department functions.
