How much research are y'all doing on each firm? I'm basically looking through their website to see practice areas in each office and if they have any unique associate development programs. Is there anything else that I should be doing?
Will interviewers be sold on "Why X firm" with an answer that says: I talked to XYZ summers, and they loved it, and I'm also interested in XYZ practice areas, which you're strong in ?
That sounds fine. Make sure the particular office
you're interviewing at is strong in the practice areas you express interest in. If you can't figure this out from Chambers and Vault, go to the firm's website and look at the list of attorneys in those practice areas to see if a significant number are in the office you're interviewing at. Smith & Jones may have a top notch antitrust practice, but if it's based entirely out of their DC office and you're interviewing for their NY office and you say that you're interested because of their antitrust practice, that's not going to look good. As far as "why X firm" questions, I think emphasis on practice areas is good, and follow it up with discussing what summers and/or attorneys have told you if applicable.
Is it necessary/good to go to each hospitality suite for which you have an interview? Or just go to the ones that you're trying to pick up an interview at?
Go to each suite. Some firms check to see which interviewees did and did not attend.
