While creative as the husband may be and God bless him LOL....the billboard move was tacky. The old fashion way of having professional contacts, cover letter, resume and presenting yourself in person in a highly professional manner...can do more for you than a billboard.
These are all very creative ways to land a job, without needing to rent any billboards. Another suggestion is to record a video resume. On video, you can show off your communication skills, personality, and passion for the job. In addition, a video resume is much more creative and personal than a traditional paper resume. This means you’ll be more likely to stand out from the pack, and you’ll increase the odds of the hiring manager remembering you when it comes time to schedule interviews and hand out job offers.
