The recruiter send me an e-mail to schedule an interview. I selected a time slot, and waited for her call, which didn't happen. She sent me another e-mail asking to reschedule the call. I did.
On the day of the 2nd appointment (which was booked a week before), 2-3 hours before the scheduled call, she changed the call's date to next week, without even sending me an email or asking if it was OK, she just changed the event's time in her calendar and assumed I will see the email from her calendar software and get the message.
I was interested in the position, so I just ignored the rudeness and decided to wait for the 3rd attempt to the interview. And even on the 3rd schedule time, I didn't receive any call just like the 1st time.
