HR was 15 minutes late for the phone interview, received a call after emailing her and asking whether she would like to reschedule. She managed to cut the call within 4 minutes, even though it was scheduled to be 45 minutes long. Absolutely no description/explanation on the company or role, not to mention any time given to ask questions. I am pretty sure she did not even have my resume at hand based on the questions asked. If you've changed your mind about a candidate, please just cancel the call to avoid wasting people's time.
