There is a test you will have to pass in order to get the job. They give you study materials for it and about a week to take the exam.

RaterLabs (previously named Leapforce, and recently acquired by Appen) has a very structured interview process that involves reading a bunch of analysis guidelines and then taking some tests online through their system. It is generally well organized and straightforward. It focuses almost entirely on your ability to do the job through directly testing the relevant skills, which seems like a generally better way of doing things than the unrelated trick questions that some companies sometimes ask. I took the interview quite a while ago, but I still remember the experience distinctly since the process was so structured. So, I decided today on impulse to actually review it since it was generally a good process. I actually meant to do so a while ago really. TLDR: Expect a highly structured and low/no nonsense kind of interview, consisting almost entirely of direct testing of the relevant skills.
