Extension on Accepting an Offer Forum

[Anonymous User]

I'm a 2L with a second half summer clerkship and I'm still seeking a first half clerkship. I had an interview with a firm last week (Firm B) and I killed it. Really hit it off with them, and they asked me when I would be able to start / spoke like I had the gig. They have a few more interviews to wrap up and they said I would be contacted by the end of this week or next. They are a small/mid firm w/ around 15 lawyers (they don't follow NALP 28 day guideline or whatever it is).

However, I have a callback interview with Firm A on April 2. I really like Firm A, much more than I like Firm B. Thus, I want to wait as long as possible to accept a potential offer so I can find out what Firm A plans on doing w/ me after my callback.

So my question is, how do I approach this situation with Firm B if they extend me an offer this week or next? I would definitely want to accept an offer from Firm B, if Firm A does not work out at my callback. I just don't want this situation to blow up in my face and have an offer rescinded by Firm B. I'm not sure if it is offensive to ask for a timeline to accept/decline an offer, or if waiting till after April 2 would be too long, even if I'm given a timeline.

Thoughts?
