Appian Intern - Hourly interview questions

I attended several campus events. All of their employees seemed like passionate, hard-working people that were serious about their work. They seem to push their interns, and regular employees for that matter, quite hard, but honestly that is something I found I liked about them. Anyone who likes to work hard and shatter goals would probably find themselves at home. I found it strange, though, how I did a campus interview followed by multiple phone interviews. You would think that having seen me in person, they would avoid further interrogations over the phone. Everything was very positive up until the last phone interview, where my interviewer did a very poor job explaining the question. Nevertheless, I made some great connections for the future. Overall positive experience.
