      Average interview

      Application

      I applied online. I interviewed at Costello Medical (Boston, MA) in Mar 2020

      Interview

      They reviewed my CV and cover letter and invited me to complete an assessment exercise. The exercise had several parts (manuscript review and questions, coding assignment in SAS or R with results presentation, draft email to intern) . It was not complicated but repetitive and took a long time. I felt they could have assessed my skills more efficiently. I completed all assignments and was invited to an in-person interview. They requested another appraisal excercise, a powerpoint presentation, and a grammar test. The application process made me feel like they don't value my time and I declined the interview offer.

      Thank you for taking the time to write a review. We recognise that we have a rigorous process, which is in part due to the very high number of applications we receive; however, we remain passionate about the opportunity our process presents for candidates to better understand the role, and for us to identify the highest quality applications. We have also received feedback that some candidates have enjoyed the opportunity the process presents to gain a better understanding of the day-to-day work the role would entail. Please rest assured that we very much value your time, as with all candidates, and we would like to thank you for your time spent during the process.

      Interview

      I applied through a referral link and was given a journal article to read and respond to a few written questions about, a dataset to conduct descriptive analysis in R, and a proofreading assessment. HR told me that they are experiencing delays in processing/interviews and told me to wait an extra week. I followed up 2 weeks later and HR told me they would have a decision to me in a week. It has been 2 months and it has been radio silence. It is also important to note that you can only apply to one job at Costello at a time - HR had me choose between 2 jobs when I had already spent time completing assessments for both jobs.
