I applied for this position through a LinkedIn ad. After filling out the required paperwork and sending in my resume, I had a technical phone screen.

The phone screen was with one of Apptio's senior engineers. It covered a more detailed description of the position, as well as further details about Apptio's business. I was asked to summarize my experience and explain why I was interested in working at Apptio. I was then asked a number of technical questions related to Java, including specifics about Java's threading model and how that interacts with various scheduling primitives like atomic types and the volatile keyword.

Following the phone screen, I was asked to come in for an on-site interview loop. This took the form of five interviews with engineers and HR personnel over the course of a day.

The technical interviews with the engineers were a mix of describing my experience and technical/programming questions, which required writing solutions on a whiteboard. The interviews with HR personnel involved general questions about my expectations for employment, any questions I might have concerning the company and its culture, and salary expectations.

After this, I was told I would be contacted within a couple of days. After four days, I contacted them for news and was told that I would not be offered the position.

Overall, the interview experience was challenging and enjoyable. Apptio has some interesting work going on, and the people seemed friendly and knowledgeable.
