I think I did alright. I mean, they probably realise that you're going to be under pressure and stress. One of my tour guides (employees currently on the scheme I'm applying for) said he had the same problem I did with one problem when he did it (not related to actual knowledge, just doing stuff under pressure).
Seriously, the problems themselves were pretty easy, I could have done them in 30 seconds flat normally, but under pressure it becomes more like 10 minutes
I ****ed up in converting a density from gcm
-3 to kgm
-3, multiplying by 10
9 at first then realising I'm an idiot and doing the right thing, but getting an answer that didn't feel right, so just throwing lesser powers of ten at the guy, before he told me that my initial thinking was correct and that I should have confidence in my convictions. I then realised that the value of the density was irrelevant to the bigger question he had asked me, and even if it weren't, the units were definitely irrelevant, and that kind of annoyed me because he had asked me to work it out in the first place
I do think I have a chance, which is a new feeling for me
I would describe the experience as "stressful but fun".
The further away from it I get the less well I think I did, but I should probably just stick to my first instincts (that I did pretty well, all things considered).
