Our interview follows the standard structure for Appian interviews outlined here. The stages are a recruiter screen, video interview with either a hiring manager or senior UXD to discuss your portfolio and previous projects, and a final round interview with multiple members of the Appian team including peers, UX leadership, and general Appian leadership.
As for the design evaluation in our interviews, we do not include white-boarding exercises and instead will send a take-home design challenge to present during your final round interview.
