Appian Solution Engineer interview questions

Appian is a very exciting company with many great attributes, but the abrupt end to my interview process gave me whiplash. The process began with a positive phone screen followed by a 45 minute video call with the hiring manager and then an automated rejection email. After 2 good conversations I actually wondered if maybe there had been a mistake. I followed up asking for confirmation and reiterated my enthusiasm. My HR contact responded curtly. A request for any feedback was unanswered as of this writing. C'est la vie. Takeaway: Appian seems to lack a human touch which may be a red flag to others.
