McKindsey developed this job recruitment advertisement for computer engineers in which to call the telephone number in the commercial you would have to solve a series of mathematical questions. It’s a quite humorous mode of job recruitment and one this blogger thinks should happen more often. Lazy people shouldn’t be able to simply pick up the phone and ring a’ ding. The job market is comeptitive right now and job seekers and employers need to get serious about the issue. Ruf Lanz designed the advert.
