I worked at Andrews Kurth full-time (More than 5 years)
Compared to most other big law firms, you will work with positive, friendly, and supportive people. The litigation section is not as much of a sweat shop atmosphere as most of the firms of my peers.
You still have the typical pressure of a large law firm to bill a ton of hours and be perfect in your work.
Advice to Management
There are a lot of young attorneys these days that need a big firm salary to pay their loans, but who have no desire to make partner. Have a non-partner track attorney position with less billable hour requirements and a reasonable lower salary.
I applied through a recruiter. The process took 4 days. I interviewed at Andrews Kurth (New York, NY) in March 2010.
Very nice attorneys, informative job description and casual conversation to lighten the mood. Very upfront about the pros and cons of the paralegal position and welcoming to any questions or concerns.
