I was contacted by an outside head hunter about this job first in December, I said I was interested but then I haven't heard from this person for months. I wasn't actively looking for a job so it didn't bother me. Then she called again and explained that the position is still open they just had some internal delays at Six Payment Services/Worldline (I believe related to the acquisition) I just had a surgery recently and the company actually had to wait a couple of weeks for me to be able to see them but they did, and I'm very glad.
I am SOO happy about this interview process, there were no "cliche'" silly questions about 5 uses of a stapler (this question actually happened to me in a different company). It was more just a pleasant conversation with a head of HR and my future Team Leader about my experiences, my expectations, office presentation. Honestly, there were no "tricky" parts.
