Give a simple JavaScript library that hashes some values to de-identify data. They ask you to fix the bugs and complete features. It is not clear what they evaluate you against. The interviewer pointed to a "bug" in the test because a serialized date was not well-formed. This was very clunky. I had to use JavaScript because of their limited language choice. My guess is that the engineer interviewing me did not like I did not seem fluent in JavaScript.
