There were 8 people including me on the day I was there, but they also said that were a two or three more groups to come, approximately 30 people total. They also mentioned that they’re not limited to the number of people they will give the jobs out to, if you meet what they’re looking for, you’ll most likely get it.
The presentation was presented with a flip chart, they provide you this along with some pens to prepare, it is on a subject of your choice, as long as it is scientifically based, they may also ask some questions regarding your presentation. The interview was 2 on 1 and just competency based, there wasn’t any technical questions asked.
The actual two days aren’t that stressful, in terms of preparation, I wasn’t told about the presentation to prepare, and I ended spending the whole night preparing and didn’t get any sleep! Bad times! So I guess that’s a heads up, other than that, practice your competenacies and you’ll be fine.
