I interviewed at their SF office. The process felt very informal and unorganized. The team was friendly and didn't seem to have a problem with my lack of experience during the initial phone interviews.

After the rejection, I asked the recruiter for any advice on how to improve but was met with silence.

How would you efficiently store huge amounts of data such that you can have a function call return the smallest value in the list?

How would you return data associated with a user's key in different formats if they did not have much in common? (e.g., webpage vs. command line)
