Similar to What is LinkedIn etiquette before an interview? I would like to know if viewing an interviewer or future co-worker's LinkedIn profile after an interview is acceptable, both while waiting for a response from the company and, after accepting an offer, waiting for your first day.
The benefit to doing this before hearing if you have been offered the position or not would be to show that you are still actively interested and researching the company, the benefit to doing this after you have been offered the job would be to get an idea of what kind of background your coworkers have.
