I just googled and it does seem like they pay 25-30/hr. It matches what they make when they graduate. It means their annual salary is $55-60K a year. My niece worked at one of those big 4s after college. She said they were supposed to get over time, but their manager made it be known it was not done. I am a customer and I pay my consultants by day and do not pay for over time.
D1 was a summer intern at a bank 10 years ago, and her pay was $75K pro-rated. I think consultants work just as hard as people in finance. I am surprised there is such a difference in pay.
