i use NALP and Martindale as a jump off to the firms actual website, most of them have something on there about the culture of the firm and the summer employment section usually lists the entire schedule for summer associates. they also have summer comments and sometimes video. it's still anecdotal but at least you're getting it from the horse's mouth. i've found that you usually can get a feel for the type of firm by the website. those that are less uptight usually have less formal/more interactive web pages. i've also noticed that some don't even have a link for OCI or summer employment they simply have recruting contact, don't exactly get the warm and fuzzies when i come across those websites.
