Quantiphi interview questions

questions are so simple and uncooked, I want to add a new column to a fact table and update how would you do that? after I answered he started to attach a new req to it, what if I had to do SCD type II.. Ist question is on a FACT table and now he want to add SCD Type II logic to FACT sounds crazy I had request him multiple times to elaborate his question, he is just simply came without preparing and not even looking my profile and asking me do you have experience in data valut (which I have not put in my profile). after interview is done I got a big mail of feedback saying not proceeding forward.. I'm just putting it here only to let ppl not waste time.
