I applied via an agency i got a response back within 1 day and had a telephone interview with their HR screener in America, i passed that interview and then had an interview with a CTM the following week, that interview just consisted of talking through my experience. I then was invited for a face to face interview two weeks later which involved a lot of behavioural questions. I then was told that i would be outsourced to a sponsor and the sponsor wanted to speak to me so i had a telephone chat with the sponsor. The sponsor then requested to meet me so i went to the sponsors offices and had a face to face interview.

First a phone screening followed by a second and and the a face to face via skype. Generally is fast within a week or 2 you know the outcome. Though may appear not serious, they usually get back to you pretty soon.
