Bulgin interview questions

I have applied via LinkedIn and was offered a phone interview initially during which we discussed my experience, salary expectations and what the role is about. I was then offered a face to face interview in their office where we had a very standard interview during which they went through a list of questions. These were pretty standard with a few technical questions, relevant to the role. We then went for a tour of the office, a presentation of the structure and my salary expectations. They sent me an offer, under my minimum requirements, which I have respectfully rejected and never heard of them.
