I feel your pain! But mostly due to the fact that I've applied for more jobs in the last 3 months than I had in the previous 12 years.
Working.com is absolutely horrible. It's the same 10 companies every single day. Even when you select "Last 24 hrs". Have you tried
www.calgaryjobshop.ca? I guess it depends on the type of work you are looking for, but I like it. And there is
www.hcareers.ca for hospitality jobs (ie restaurants, hotels, etc).
