First step is to send the resume, Cover Letter and Writing Samples (+ references if possible -> this makes a difference). Then if positive they invite you to an online interview with 4/5 interviewers between HR and Senior Researchers.

I was asked to conduct an online Zoom interview with two members of the research team, each in different offices. Friendly interview, did not seem very well-coordinated, questions were standard, both about my past experience and interest in the job, requirements for the job.
