First you do an HR interview. 1-2 weeks later you will get an assessment - either make a decision on whether to accept papers in Nature, and give reasons. The other options is to assess recent literature and argue, why Nature missed out on publishing, or why you think something in Nature should be published elsewhere. After passing the assessment, there is usually a 4h interview with the entire team, including a manuscript assessment drill. There are long waiting times between assessments and interviews.

Applied the online through the workday platform. In the system, submit the assignment according the JD, which should discuss a recent paper which excites you in your field, and CV along with a cover letter including your background and motivation for the position.
