I worked at Nature Publishing Group full-time (More than 3 years)
Nature and associated research journals have a good reputation in the field, but the nature of scientific publishing is changing a lot so there is some uncertainty about whether this will continue. My direct manager was great but I could see quite a bit of inefficiency in the company. Good location.
See above about changing nature of publishing. Pay is not that great either.
I applied online. The process took 2+ months. I interviewed at Nature Publishing Group (New York, NY).
Spoke to the Chief Editor of the journal on the phone. Completed a written exercise including assessing recent papers published in the journal, pitching topics for reviews, and suggesting improvements for the journal. Was promptly invited for an interview and promptly offered the job after the interview. Interview consisted of a manuscript test, and several informal meetings and discussions with other editors. Salary offer was much lower than initially suggested by the Chief Editor, and negotiations were very tough. Very short time frame for entire negotiation process.
