I just applied for a job and had crazy fuck

So ive been shooting amateur modelling photos and some were even in professional studios. My gym was suffering and i had to barely eat just to maintain my body. Then i saw a job opportunity on the internet, they were asking for real models with some expirience in the past but i applied anyway. Few weeks went by and i even forgot about it when i got the call. I remember i was really happy even tho nothing was done. I took my dress, even paid for my hair and makeup to be perfect. I waited around hour in the hall even tho noone else was there. They invited me finally in. There were just two older guys and we started talking and they questioned me about everything i ever did. When they told me all i had to is film few ads monthly and thats it, and salary was like 3 times bigger than my dads i told myself i gotta get it. Since i told them i got no expirience they told me i need to prove myself to them in order to get the job, and i gladly accepted with the smile without knowing what they really meant. When everything started everything in my mind was just focus that if i endure it and please them i will be able to make so much money. Once they were done they told me they will call if they choose me. And they didnt. I still feel dirty for letting them do all sort of things just to get nothing in return.
