Point is.
What's the use a of a brand name like Accenture if it offers the lowest pay and people also quit in search of a higher pay regardless of the brand...

Brand only important in the first few job..

After a while, you just hop across branded company. Cause one brand opens you up to another brand.
And you just collect them all in your resume.

So just choose the highest paid for your internship. Period.
Nobody takes your internship company seriously.
