Candidates texting interviewers?

Used to be job candidates would send thank-you letters to interviewers. Now they’re going high-tech — and employers might not be happy.
According to a recent Wall Street Journal article, some younger job seekers have taken to sending thank-you text messages — sometimes just minutes after leaving the interview.
Also, recruiters say candidates are using “text-speak” (i.e., “Thnx 4 the interview : )”), both in actual text messages and in e-mails. And some have been “friended” by candidates on social networking sites.
Not surprisingly, such antics usually mean the person won’t get the job.
