Another data point for Australia - I recently applied for a job with a description that included quite a large range of technologies, all of which I happened to know reasonably well. Was contacted back only to find out that not only was it not a single position, but it wasn't even for the one company. The recruiters had just pulled together all of the requirements from multiple jobs and put them all in one ad, which would have been fine if they'd made that obvious. Maybe to save advertising costs? Whatever the reason, it didn't leave a good impression.
