I applied online. I interviewed at Costello Medical
Interview
The interview process was well organised overall. It began with an initial screening interview that was self-recorded and timed, which wasn't a particularly positive experience. If successful, candidates then had to complete two exercises: a proofreading task and a statistical exercise. The final stage was a 90-minute interview with two different panels, after which successful candidates received an offer.

Question 1
Why would you like to apply for the statistician role? Why Costello medical?
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.

The interview process took around a month or so from the initial application. The process begins with a virtual interview then proceeds to a project and proofreading assessment. If you pass this round, then you move onto the final round interview with multiple interviewers.
