      Analyst/Medical Writer Interview

      Difficult interview

      Application

      I interviewed at Costello Medical in Jul 2024

      Interview

      I applied for the full-time, entry-level Analyst/Medical Writer role in July with a cover letter and my CV. I was asked to complete two assessments : a written question/answer-type assessment based on a complex scientific paper, and a proofreading task. The written assessment was quite time-consuming, with around 5 questions. The timed proofreading task was to be completed in under 1 hour. This involved finding around 50 errors in a document and writing a summary. This was also quite difficult, and showed the level they expected from candidates as these completed assessments were supposed to be "client-ready". Having successfully completed these tasks, I was invited for an interview. I was asked to prepare a 10-minute presentation on a 20-page long, complex paper. I spent a considerable amount of time on this task, making sure it was also "client-ready" and matched their standards. The first part of the interview was my presentation, followed by questions from two interviewees. The questions were already prepared prior to interview, which showed a lack of interest in the work I put in as I was repeating a lot of what I had already said in the presentation. However, there were also some more difficult technical questions which required wider reading and research, which I managed to answer well overall. The second part of the interview was an hour long, with another two members of the company, which involved behavioural and situational questions. The interviewees were very friendly but, again, the questions were from a standard collection of questions and therefore felt very impersonal. I was told that for the final stage of the interview I would be meeting with a division head, and therefore might also need to repeat my answers to identical questions they may have. After a week, I quickly received a rejection email. I appreciated the feedback that was given, such as some evident stress/nerves during my presentation. However, for the interview questions segment of the interview, I was told I did not highlight enough why I wanted to work at this company specifically. This caught me off guard, as I wasn't specifically asked why I wanted to join them and had done considerable research on the company, which I managed to highlight through some of my other answers. However, I felt that if they wanted a full answer to that question they should have asked, and not expect me to answer indirectly through behavioural/situational questions. Overall, it was a pretty lengthy and complex interview process for a entry-level job. I assume they are not actively looking to hire and will only hire a "perfect candidate". Having done well in the assessment process and having had feedback from my application for the full-time role, I decided to email HR to ask if it was possible to be considered for the Analyst/Medical Writer Internship. I was told to apply directly through the link, and restart the whole process again. I therefore submitted my CV and cover letter again, this time highlighting what I learnt through the previous interview process and why I would do well in the internship. I was emailed with two assessments to complete, again. This written assessment was a tad less tedious than the last, so I completed it relatively quickly. As for the timed proofreading assessment, they sent me the same one as last time! Having done very well last time, I completed and sent it over again. However, this showed the lack of interest in individual applicants, as I had stated in my cover letter I had completed the assessments already, they should have sent me different ones - although I can't complain, I did well again like the last time and was invited to interview. This interview was 45 minutes, with two friendly employees. I was asked the same, basic situational, behavioural questions as the last interview. With the feedback from my last interview, I made sure to emphasise in almost every answer why I wanted to work at their company. I was also asked why I preferred to apply for the internship and hadn't applied for the full-time role (made things a bit awkward and showed again that they don't show true interest in candidates, as this was clearly stated in my cover letter). A week later, I received my rejection email. This time: no feedback, with only a simple, standard, cold message saying there was a field of competitive candidates for this role.

      Thank you for providing a comprehensive overview of your experience – your feedback is helpful to us and we use it to support us in further shaping our processes. We acknowledge that our application and interview process has multiple stages and is thorough in its nature, however this is intentional given the high standards and technical expertise required for our roles. We aim to ensure a thorough assessment of candidates’ skills and motivation, which involves assessing candidates in a structured interview to provide a fair and standardised process. Our permanent and internship roles are held to a similar standard as the nature of work for each role is the same. The internship provides individuals with an opportunity to trial the role in a 3- or 6-month internship before committing to the job, hence the proofreading assessment being the same. We also use the same assessments per role to provide a standardised and fair process for each candidate, rather than providing different assessments to each candidate. Your feedback is very valuable, in particular around your experience of re-applying, and we will consider it carefully alongside our colleagues in Talent Acquisition. We appreciate your perseverance and interest in Costello Medical, and we wish you the best in your future career pursuits.

      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!
