I have first been contacted by phone, had a very pleasant conversation where I could describe my CV, motivation and experience. The person who contacted me was very patient to reply to all of my questions and curiosities, and I was very happy to proceed with the interview process. Later, I had a panel interview, using skype with three professionals from Oxfam team. I had to address a practical issue, regarding a hypothetical project. but I had time to prepare a reasonably detailed presentation. They made me feel very comfortable: no tricky questions just very curious about what I think was relevant for the job holder. Finally, I had a specific skill test, but for the ones working in the sector - it was very easy.
