I applied online, this was just a CV and covering letter. I then had two interviews with a Business Manager and a specialist. After the applicants had been whittled down to two or three I had a skype 'chat' with the head of department who was based in NYC. The process was very straightforward and HR was very good about getting back to me on time with feedback. I was offered the job the afternoon of my skype chat and accepted then and there.

if they are looking for someone to fill the position immediately, it does not take long. after the initial meeting with HR, met with a few key members of the department, they checked my references, issued a background check and got the offer
