online and done in your own time without someone directly questioning you so due to blind questioning and non live interview it was hard not to overlap answers which made it very frustrating.

Question 1
Standard behavorial and technical questions as previously mentioned.
I applied online. The process took 4 weeks. I interviewed at Costello Medical in Jun 2025
Interview
The interview process was similar to what others described, with a strong focus on proofreading. I found the proofreading requirement quite strict, even for a statistician role, which might be extra challenging for non-native English speakers like me. I also spent a significant amount of time and energy on the assessment project—it was quite demanding compared to other application processes. However, I appreciated the opportunity to work on a technical project and gain new skills for my resume.
