The interview was short and purely technical. There was just an introduction by name, and then it went straight into answering the question posed to me. It was pretty impersonal, but I didn't do all that well on the question anyway, so I suppose I can't complain.

Afterwards, there was about a week and a half before a personal phone call informing me I didn't get an offer. This was followed by an email with some instructions on moving forward and potentially applying again down the line.

The initial question was essentially a portion of the Merge Sort algorithm, with a generalization to an arbitrary number of inputs as the follow-up.
