TransPerfect Account Manager interview questions

Never actually got to interview with them. I was offered a phone interview but had an emergency and sent them an email explaining what happened. Asked to reschedule for the next day. Instead of saying no or even responding to my email, they just canceled the calender invitation. That's it. No other contact after that at all. It is fine if an interview reschedule is unacceptable but it's extremely rude not to even directly say no. Unprofessional, entitled a-holes, no wonder everyone hates working here. Looks like I dodged a bullet.
