Before being considers for an interview, applicants are required to answer a lengthy questionnaire asking for likes and dislikes about broad technologies categories (Java, C++, Windows, Apple, and while they don't ask directly, they indirectly ask what you spend your free time doing.
From the process and response from the company, they are looking for total technology nerds. If you don't spend your free time writing code from an open-source project, they consider that a "red flag" and eliminate you from consideration. They look for people for whom the command line is the primary form of "social" interaction. The well-rounded need not apply.
The job description stated: "Willing to work off-hours", read: Always working after hours - that's the real "red flag". Apparently the trend towards work-life balance is lost on this company. Don't waste your time on the questionnaire unless going home to write more code and play video games is the highlight of your day.
