The interview was nothing out of the ordinary, as far as tech interviews go. However, neither of my interviewers showed up, so I had to wait 30 minutes for a couple of random employees to be grabbed to interview me, which resulted in my interviews being cut short.

After the interview, I was told I'd be contacted within 2 weeks. It took 4 weeks, two unanswered e-mails, and a phone call (which went to voicemail) before they sent me an auto-reply email saying I hadn't gotten the position. At that point, I didn't even want it anymore. And they still haven't reimbursed me for travel, to the tune of $500.

You have a bag of coins, and you can place them on each hour on a clock. For each coin you put down, it must be its own value away from the previously placed coin. So if you have a penny on 3 o'clock, and you want to put down a nickel, you place it on 8 o'clock. The game is won if you find a sequence of coin placements that results in each hour being covered. How would you design a test to determine if the game is won? Program the game. Optimize.
