      Difficult interview

      Application

      I applied online. The process took 2 months. I interviewed at Costello Medical (Manchester, England) in Aug 2023

      Interview

      Around a week and a half after I completed my application (CV and cover letter), I was invited to complete a written assessment, which consisted of creating a graph to present some data and answering some questions about a clinical trial data. After around another week and a half I was invited to an interview and asked for my availability. I was extremely busy at the time writing up my PhD thesis, so I asked if I could have some extra time to prepare for the interview, and the recruitment team were very accommodating and gave me two full weeks to prepare. The interview lasted around two hours and I was interviewed by people with different roles in the company (from Senior Analyst/Medical Writer to the Scientific Director). I had to give a presentation about some guidelines on a new drug, answer technical questions about the guidelines and then had some more general motivation/competency based questions. Some of the technical questions were quite tough and I wasn't sure of all the answers, but everyone was very friendly and I actually really enjoyed the interview! Around a week and a half later I got a phone call offering me the job.

      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!
