I had a top line introductory interview with Human Resources, which was then followed by a writing task. After submitting the writing task I had an interview with two members of the Science team.

Interview with HR first who will ask for salary requirements. If they are too high yoy won't get far. May be preferable to say " going rate" and not give a number. You will meet with hiring manager who is a senior level writer/ scientific director or team lead. Writing test is required. Be sure there are no typos or grammatical errors and do not plagiarize or use AI to write any part of it.
