Our process

We break it up into 3 stages:

Initial call with Luke, our Talent Acquisition Partner (45 mins)
A previous experience interview where you will discuss your journey so far and ways of working with Paul, our Head of Data Science (45 minutes)
A technical interview with one of our Senior Data Scientists (1 hr)
A culture interview with a bar raiser to see if your work style fits our processes and values (1 hour)
We’ll let you know if you’re invited to an interview or not. But, as a small team with a lot of applications to consider, we can’t give personal feedback on each application.
