Factors important to me (in order of preference): Quality of work, Reputation, Exit options, Quality of Life.
Simpson: Obviously, great reputation. I think I would be perfectly fine if I end up choosing Corporate, but their Lit. is concerning since Corp. has such a heavy presence at Simpson. Their IP/Patent Lit is tiny. Somehow I feel like QoL might be better here as compared to some of my other options. People were extremely friendly and nice. The no billable hour requirement sounds nice at least on paper, but in reality probably the number is pretty high anyway.
Kirkland: Obvious Lit. reputations. They wanted me for IP Lit for sure, but after the big departures in their IP dept. I am not sure of their strengths in IP. But still could be great for general Lit. People I met were generally very smart. But K&E's reputation for "free market system", which I read as dog-eat-dog world, kinda scares me given my personality. For some reason, there are lot of people going to K&E in Chicago or DC but none or very few to NYC office from my school.
Quinn: They seem to be on a up-swing. I hear about excessive emphasis on hours (2400?). I am not necessarily shying away from BigLaw hours, but if I had a choice among equally prestigious firms, I would love to have some QoL left. They are also pretty good in IP/Patent Lit at this point and also like their no frills work attire (speaks to my engineer's heart well

Patterson Belknap: Was tempted w/ their lean staffing model and their emphasis on Associate training. Seems to be the place with a better QoL, but not sure how much more compared to Simpson or Kirkland or is it worth walking away from some of the other options. People I met very humble and extremely nice. No frills attitude.
Which one would you choose if I have the same options?
