LinkedIn interview questions

I was contacted by a linkedin recruiter on linkedin. Had a quick phone screen with the recruiter, who made a fantastic job of selling the position to me. I then had to do an online set of coding exercises which I describe below. I didn't find it too hard, but I do have a problem with writing code / think in front of people in pressure settings such as an interview. The experience was positive, minus one minor thing for one of the questions where I felt the interviewer was confused as to what was expected and did not clarify. Instead, he simplified the problem, which made me insecure as to what result that would have. The coding exercise was done on a collabedit instance while on the phone with the Senior SRE. Both people I spoke to had a nice positive and friendly tone. I would like to try again in the future.
