AskforTask interview questions

Went in for interview- they accommodated me by doing it at 630 but even though I was early they started the interview 5 minutes late. No one was ahead of me. The interviewer was really casual which is fine but she should have told me at the start that it was a PART-TIME role. She waited until 15/20 minutes in to inform me it was $15/hr with full time hours - she didn't even say what the hours were. On top of all of this there was not one mention in ANY job postings from this company about part time.
