Gauder interview questions

I was sent to an online assessment with some numerical, business judgement and procurement related questions. After passing the assessment, the first round of interview is with CEO/Founder, I asked a questions about why this position has been re-opened, the answer gave a little clue that they have been through a few candidiates and nobody fulfilled their expectations, as a small start-up, the high rotation of candidates hurts. I think they also are search ideas what kind of profile would fit better and the best.

1. An intense online assessment was conducted before the first round interview(not sure how it's related to real job experience) 2. 30 mins interview with founder with mostly general questions
