New one now that I'm desperately job-hunting. I hate it when places let you upload your resume, then tell you to enter all of your work information. I just did! It's easily accessible! It's neatly organized with dates and phone numbers and job descriptions! Everything you could want, already uploaded! So why do I have to enter everything that's on my resume again?!
One that made me so crazy I wanted to smash the computer made me enter what state each job had been in. But I couldn't type 'Virginia' or 'VA'. I had to go to their search menu, find Virginia, click on the tab to select, and upload. It made me do that for every job I've had over the last ten years. And in some cases, asking for addresses of businesses that have closed, and refusing to accept that they have neither an address nor a phone number they can call.
