My observations on job seeking.
1. Unless the job is exceptionally technical or regulated, 75-90% of your resume is simply about your ability to formulate a coherent, well laid out, and properly formatted and spelled document.
2. Unless it is a rigorous panel process, 90% of interviews are about your personal presentation and interactions with the interviewer.
3. 99.9% of employers with any kind of HR dept. or HR training will only confirm job title and employment dates these days, no matter how good or bad an employee was, due to liability concerns over lawsuits. This is so bad, that many hiring managers won't even bother to call past work references, unless the listed businesses or job experience seems suspicious.
So unless it's a really small town, or a very tightly regulated industry or job type where a reputation and personal history can follow you around, being fired isn't a big deal at all. You can just say you were downsized.
Getting hired and reviewing past job history is a LOT like dating. If you meet an attractive person of the opposite sex, you begin to feel that you're "in to them", and want to see more of them, how many people would believe negative information from other people they don't know personally, and instead just discount it as 'sour grapes' etc.?
Unless you've got some kind of crazy job history that will make an employer question you, in reality, getting hired is more about being the attractive person, and then not fucking it up once hired, than it is about the minutiae of your resume.
