Fortiva Financial interview questions

Questioning was all over the place and was asked to do quite a bit of pre-work for contract consideration up to 40 hours for consideration for a 6 month contract. I was not offered coffee or water and before the interview told not to "expect lunch" since it was during the lunch hour, which i would never have expected but found rather rude. On the way out the interviewer told me twice where the coffee shop was downstairs so I could buy myself a coffee on my way out. Questioning was vague.
