      Medical Writer/Analyst Interview

      Dec 11, 2024
      Anonymous Interview Candidate
      No offer
      Neutral experience
      Average interview

      Application

      I applied online. The process took 3 weeks. I interviewed at Costello Medical

      Interview

      I received a request to complete a written assignment and a times skills test within 5 days of submitting my application (they said you would hear back from them regardless of if you are successful or not which is very uncommon these days, I really appreciated that). The written assignment and timed skills test were extremely time intensive to do without even having a short interview beforehand. It is a lot to ask of someone to do this kind of work unpaid when they are already looking for a job. I personally had a fun time learning about the content of the clinical trial I did my written portion on, but aside from that I find it bizarre that as applicants we can't speak with anybody in person before this part of the interview.

      Question 1

      Written assignment assessed reading comprehension for clinical trials.

      Analyst/Medical Writer Interview

      Boston, MA
      No offer
      Positive experience
      Difficult interview

      Application

      I interviewed at Costello Medical (Boston, MA)

      Interview

      I passed CV screening and went about the first round (proofreading + writing assessment). They gave me a week for that; the writing assessment involved answering some questions based on a research article, and the proofreading assessment involved making 50+ edits to an article and writing a 300 word summary of an article in 1 hour. The recruiter + some others review it, and I was then invited to the final stage interview in Boston. It was further away, so I did it virtually -- 15 min presentation w/ questions to an analyst + senior analyst, you present on a report with a similar topic to the writing assessment, and 45 min behavioral interview with a more senior leader. Interview ran long (they ask a lot of presentation followups) and I ended 25 minutes past the timeframe haha, but all good I hope. Interviewers were all sweet and gave gentle feedback/broadened some of your responses in the moment, if needed. It was a bit tough, but make sure to prepare well, and you got this! Still waiting to hear back and will update the result later.

      Interview questions [1]

      Question 1

      Tell me about yourself/why this role? Why Costello specifically? What would you do if a client told you that you made a mistake in your work? What kind of culture are you looking for in your workplace? A time you managed multiple deadlines? Your background in science and/or writing? Make sure to ask your interviewers some good questions!
