I 've resolved the test code but I was a bit slow ,then they didn't go forward with me in the afternoon. They didn't know I came from Verona!!! They were surprised! I asked Barbara if there was some refund for my expenses. She said they consider its only for students :-) no for worker engineers :-) and she didn't pay back anything. My expenses were around 200 euros. (flying and rent a room for 2 days ) Serious companies pay back expenses if they are very interesting to see candidates. Bad experience, I don't advice it to anyone, lost time and money!. They don't care you have flown from Verona and I've spent 3 days. If you are in London you could do it.
