yes there is a serious back log of people in the works.. QA has been in a constant state of hire for at least 6 or 7 years now as I recall.
Some of the recent problems are due to the termination or re-designation of the former staff members that used to look after this department ( not very well either).
but also keep in mind, not only do the reservations and coordinations have to be done for your interview, but you must also have a visa to enter this country, and that also causes a paper shuffle delay.. among may other things. not to mention that accommodations in hotel can be very difficult during times of large sporting events, conventions and the like.. there are only so many hotels in the desert village you know.
