yep apparently communication is not the best skill of QR....I realize that!!!
anyway this was my experience and with me they weren't so clear. Anyone here has his own experience and plan, so in my case if I applied for a position and you (company) call me for an assessment in that position, I'm expecting to be call for that position otherwise, I have the right to save my annual leave for my family or my self instead of spending it to travel in Doha and prepare myself for an interview for a month before. Again this is my point of view.... Cheers
