I sent an email to the consulate requesting confirmation of that date (as i'd love to make it and im off to thailand) and the responded 18/06 is when it will be. I haven't received any official confirmation regarding it too, I assume it will come through with our placement details. Here's a quick snippet of my email correspondence;
"The Q&A is definitely confirmed for June 18, but I am afraid it is not in the evening. It runs from 9 to 5 with a break for lunch, and there is usually an optional dinner in the evening.
I am afraid I don’t have any further information regarding the placements. All we know is that we will receive them sometime in May, but expect that it could be later in May as the interview results were delayed by a week or so too. Please be assured that I will send them out as soon as we receive them."
