Disgusting can summarize it pretty much , from an HR who always schedule a call and call u after 2 hours after or before the scheduled time ( Thats not whining cause u dont know when will your boss be next to your desk checking up on u :) to see u making an interview for another company ) , to a technical interviewer who calls u yet again earlier than the scheduled call just cause he wants to be early for his meeting at 12:45 , why should i care about your problems, this a test for the love of god .

First of all there was a HR phone call to make sure that you can speak English and understand it, after that a technical phone call to solve an easy problem on strings after 5 or 6 days they called me to attend an on-site interview and it supposed to be another one but they never call me or send an Email to inform me if I'm accepted or rejected !!
