Abodewell interview questions

I applied online and got a data challenge first. 7 questions, including coding, sql, probability calculation and prediction. Then a phone interview, most was behavioral questions. Got rejected after this...

I applied online. First step was a call with their head of product, which went well. Then they gave me a take-home assignment, fairly open-ended. I didn't receive a lot of feedback, but it was a pretty work-intense assignment. About a week-and-a-half later, rejection. I understand that they were looking for creativity with the open-endedness, but it's pretty ballsy for a small not very well-known company to demand so much from their candidates.
