never wait. ask the questions you want answered. jobs are NOT just about the employer. if you have any skills and you're qualified for the job, ask. if asking an important question (to you) keeps you from getting the job, is it really the job for you? are you a good fit for them? important... yes. is the job a good fit for you? probably more important in the long run if you're looking at a career position as opposed to a job to pay the bills. employers should be happy that you're asking questions. to me it should say, "i'm looking long-term at this job." of course, today's work environment tends to look at people as disposable, but that also lends itself to a culture of failure, low goals, low expectations and shoddy output. it's takes quality to produce quality. companies cannot succeed in the long term with such an environment. in the end, what do you think you're worth?
