Day 7 Check Social Graph and Networking

Check yourself

Ten questions on the three designs from Day 7, people you may know, connections and the timeline. All three refuse to walk the graph while a user is waiting, and all three have a problem with people who are far too well connected. What differs is when the work happens and how much staleness each can accept.

You will be asked 10 questions drawn from a larger bank, so a second attempt will not be the same paper. Answer from what the designs actually said, not from what sounds sensible in general.
