Well, here we go I passed!!!!!!!! Minor revisions, which I was expecting, all in all an interesting, and intellectual conversation, hard but not as difficult as I expected. To the weekend, champagne and a chance to realise it is Christmas!
Congrats! I only got asked one generic question ('what made you choose this project?'), all the rest were very technical and I didn't know many of them, but tried my best to show the thought processes.
