HP and Amdahl have hired hearing impaired employees and their mangers have learned sign language in order to communicate with them. But don't bring up the fact that you or your kids are regularly ill with PMS or colds or flus. Part of the issue is medical insurance and productivity. The more people are ill and use medical benefits, premiums may increase for the company, and potentially, you, the employee. Other factors could include how much the company is willing to subsidize the cost of insurance, but often, the more sickly the employee population, the higher the premiums.
Many people have to hold down more than one job to make ends meet.
Ideally, your day job will have fairly regular hours and you can get to the second job without problems. However, if the day job employer asks about your ability to work overtime, think about what you're going to say. If you say you have a second job, the employer may think you are not fully committed to this job or are having financial difficulties or other perceptions that you are not a good candidate. People often get into real estate and may even list it on their resume that they have a license. It has nothing to do with the job you're interviewing for.
