The interview process was fairly straightforward and very pleasant. My experience may be a little different from the "standard" process, as I arranged an informal meeting with the hiring manager while attending an industry trade show. This resulted in a more formal, in-person interview schedule with sales and marketing leadership.
One interesting aspect of the interview process was the request to put together a presentation (PowerPoint) and pitch one of their solutions to the sales leadership, with the idea that they were the customer. While I hadn't ever been asked to do this for any interview before, I found it to be a good experience which provided me great insight into the company and its solutions.
