First question I was handed a laptop with Xcode running on it. The assignment was to write a super simple browser app that used substitution (or "regular expression", as the interviewer referred to it) to replace any instances of the word "Nest" with something arbitrary (e.g. I chose something like the name "Glassdoor").

For the systems design question, the guy described a real world scenario where a series of events have to happen in order to fully bring up a device. - auth (to get a token we'll call "A") - fetch info from home + devices (with the A auth token) - fetch current weather information (using the home/device zip code) - reach out to a third party service with our A auth token to exchange, or get, a B token - fetch data from service using B token how would we structure the sequence of events or dependencies to come up with the fastest boot up (or bring up) sequence possible?
