Written application (CV and cover letter), video interview, modelling exercise, writing exercise, proofreading exercise, interviews (approximate duration of 6 to 8 weeks). The HR team is very response and answers questions throughout the process - very easy to interact with and positive experience overall during the interview process

Question 1
Several modelling questions (about the technical exercise and own experience)

I applied online. The process took 4 weeks. I interviewed at Costello Medical (Boston, MA) in Oct 2025
Interview
They had a fairly transparent and communicative interview process, aside from the exact assessment grading criteria. Their HR is kind and willing to give feedback on your work when asked.
