Considering how rude HR and hiring managers have become, getting even a letter is really awesome. Most don't see the point. They claim they're too busy, it costs too much money, blah blah blah. Then they complain how rude job seekers are, not calling them back, showing up late. Talk about calling the kettle black.
I've found it takes me about 6 weeks to find a job. It will probably take me longer once I land, because I plan to be picky lol. Oh, and demand at least one Friday off a month. Hubby has Friday/Saturday off. If we ever want to be able to take weekend trips, that's going to be needed.
