The interview went well, they asked a lot of questions so make sure you know all the answers about your petitioner and partner. You are not allowed any electrical items of any kind, this includes remote controls for your car and earphones. I forgot about my earphones in my bag and had to throw them away in a dustbin! But I was allowed my hearing aids.
Make sure you get there as early as you can. Apart from that, everything went well and I was approved.
