It is if you see it as "black magic". Magic is intent, not colour, so you should ask yourself what you think it is? Is it manipulative? Does this give you an advantage? But do you need this job to survive? Is it your dream job? Are you excited to work there? Weigh the pros and cons and decide for yourself if it's right or wrong. Personally I'm fine with a little push before an interview to help yourself along, especially if you really want the job.
