This job was based in the U.K. The application process had positives and negatives.
I'll start with the negatives: The application process took a really long time - I didn't hear that I had been offered an interview until three weeks after the application deadline had passed. I was notified of the interview two weeks before the interview date, but wasn't told the outcome of the interview until a week after the interview had taken place. From the initial application deadline to being told I was not being taken to the second round of interviews took around 42 days. The other downside was that recruitment never answered any of my emails when I had requested information on one or two occasions. For example, before applying I had requested more information about the job role, but nobody got back to me.
The positives were that everyone I met at WWF- UK on the day of the interview were very friendly, from the reception staff to everyone on the interview panel. The three interviewers seemed very nice, and did their best to make me feel at ease.
The interview itself was different to how I had expected, there were no waffley questions such as 'tell me about yourself' or 'describe yourself in three words' or 'why would you be the best person for this job' or 'what animal would you be' - none of that. All the questions were very specific and wanted to get straight to the heart of my experience, and exactly what relevant experience I had, and how I had gone about it. They wanted clear examples of relevant experience, and wanted to find out my understanding of how things (i.e. project management or stakeholder negotiation) should be done. There didn't seem to be much room for talking about other skills and experience, or trying to elaborate on why I could be best for the job. This is the part I found difficult - I was quizzed in some detail about very specific experience, but there was little room to 'show off' in other areas or tell them about other things I had done or achieved, or additional skills I had. I also had to do a 5 minute (pre-prepared) presentation. The topic, set by WWF, was the impacts of trophy hunting on wildlife conservation. As this was a Technical Adviser role (which would involve giving expert wildlife conservation advice) , candidates were expected to have a strong knowledge of conservation science, hence the technical nature of the presentation.
My experience may not be typical of WWF interviews for other job roles - I suppose different interview panels ask different questions, so an interview for an HR or Communications position would likely be completely different.
