Context Creative Designer interview questions

I had one interview with the partner/creative director and a second interview with 2 partners and the associate creative director. I had a good impression of the associate CD as well as one of the partners--however I had a less favourable impression of the 2nd partner I met. The second partner seemed very domineering and cold; I felt as though I may have trouble working with this person. The interviews were pretty easy and short--the team didn't even review my portfolio with me which is pretty uncommon for a designer interview. I ended up receiving an offer, and was trying to make a decision between a couple offers i had received, as well as some upcoming interviews. I ended up not taking the offer, and the following correspondence via email by the Partners reinforced that I made a good decision. I tried to leave my last interaction with them amicable & wishing them the best of luck, but I don't think my message was received or understood for what it was meant to be.
