Bluebird International interview questions

So my interview was scheduled at 8:30am. Was continuously reminded about it by the consultancy prior to the interview day. When I reached the venue, the office was empty. Not a single person around. After few minutes a person asked me to sit inside. He had no idea about why was I there. He didn't have clue about the scheduled interview. I just sat at venue for sometime browsing stuff. So the person returned back saying I have to give written exam. This was shocking to me as I was told that it's going to be a face-to-face interview. So, that's it. Even before the interview they proved that the management is unorganised. I didn't wanted to work for such organization where time isn't respected. So yes I declined that interview and left the venue.
