Unfortunately that website's information is rather out of date....there are a lot of varied areas of employment for OS (Int) officers but clearly the main focus is the provision of current air int to deployed forces. The JO cadre is under significant pressure as the OOA deployment rate is one 4 month det every other year, on top of whatever FU dets they have participated in. (Something like 25 concurrent dets for a cadre of 140ish JOs - not all of which are available to deploy). This is not a sustainable situation and steps are being to reduce the pressure where possible.
There is likely to be a hold prior to the JAIC (Joint Air Int Cse) although the reduction in throughput of students this year might well reduce this. Likely first tours include the AWC, one of the Stn Int Cells as deputy to the Stn Int O and JARIC. There is now a CR programme to be met during the first tour and passing this is not a foregone conclusion. There are a couple of JO posts in the bunkers at STC and PJHQ but these are not ideal for first tourists.
It's a challenging job and you can expect her to spend a lot of time away on ops and exercises!
