I applied online. The process took 2 months. I interviewed at Climate Science (London, England) in Jun 2022
Interview
For a very low-paid position (practically minimum wage), there was a long interview process (3 interviews) and time-consuming trial task. They then let weeks go by without an update, after saying they would respond within a few days. For jobs that are ~£26,000, they should not take so much of your time to apply.
Interview questions [1]
Question 1
They asked typical questions about background, interests, goals, etc.
