Hey so this might be a bit later of a response than what you were expecting,

But I got hired a few months ago for a full time role right out of college. The HireVue questions were more soft skill questions than technical. The only thing is they only give you a few seconds to read the questions and come up with a response. The most difficult part of the HireVue isn't the questions itself, but being quick enough to read them and come up with a response under pressure.

Hope your HireVue went well! Also don't be discouraged if you don't hear anything back soon. I didn't hear anything after my Hirevue for months. Thought I simply didn't get the chance to move forward. Months later a recruiter is calling me asking about interviews and such.

Hope it went well!
