First, the assessment center started off with a small tour of the Leonardo building.
Afterwards, we jumped straight into the presentation/interview depending on what group you were put it. I did the presentation first, and what I noted is that the initial advice I was given was quite misleading - the people you present to care deeply about the content you mention and will ask a plentiful amount of questions about anything you mention. I remember briefly mentioning quadrature modulation and then the next 5 questions were focused on that... make sure you know everything 100% when you present.
This then lead straight into the interview - yes, the same people who I presented too also interviewed me afterwards. I'd say this is the easiest part, it's basic competency based questions such as "when have you worked as a team" and "how have you motivated someone on your team to work harder".
The final stage of the assessment center was the written essay, which lets you choose from a set amount of questions (I believe it was 6 when I went) and then answer it in regards to a specific context. This was fairly straightforward, although I remember missing a point which came back to bite me in the butt when I received my scores through the feedback over the phone, which I'll get to know.
After the whole event, I was informed I hadn't got the place. I wasn't too upset, considering it was my first assessment center (and first in-person interview) and it was only my presentation that was bad, although it was very bad. The rest of my stuff was great, but again I cannot stress enough you must be an expert on exactly what you are talking about. My presentation was rushed which ended up being my kryptonite. I would always recommend asking for feedback at the end, as it's always good to learn what your weaknesses are. The lady over the phone was very kind and helped me throughout everything, even when my coach decided to be 45 minutes late (I arrived 5 minutes late).
