Astrolab interview questions

Two rounds of video interviews and an in-person interview, roughly three weeks later. A fairly straightforward process until the in-person interview which they stopped roughly two people into the five. After having flown cross country to 1) Not really ask questions during the presentation, 2) Deciding to stop the process roughly 40% of the way seemed weird. On a positive note I did appreciate the decisiveness yet felt it would have been better to ask questions during or following the presentation.
