After each attempt you get scores across core competencies, your strengths and what to improve, and a human-written model answer to compare against. Casper responses are placed in a quartile and MMI stations get a grade. You can also share a link to get feedback from peers or mentors.
Questions are timed the way they are on test day, with video and typed responses, multi-part questions and follow-ups. For MMIs, an interviewer avatar reads each prompt aloud.
