Write a function that accepts an array of ints and a target number. If two of the numbers in the array can add up to the target, return their indices. (aka Two Sum)

Write a function that accepts an int x and prints a spiral of "#"s so that the number of "arms" in the spiral equals x.

Write a function that accepts a month and a year, and draws a calendar view of that month.

Given a non-negative int x, repeatedly add all its digits until the result has only one digit.

I think I was also asked something that involved a tree structure, but I can't remember the specific problem.

I thought all of those questions were fucking stupid. The good interviewers, IMO, gave me a "take-home" problem of building some mini front-end app that hit an API, and the really fun one involved reverse engineering an unpublished API - that's how I got my current job.

I spent a lot of time studying the h5bp Front End Interview Questions[1], and the only front-end specific question I was asked was, "What is an SVG sprite?" during an initial phone chat with a CEO.
