Within a week of submitting my application I received an email with three exercises. Two were on haircuts and the last was exercises that displayed your ability to work with excel. The next step was a 30-min phone call that was highly quantitative and consisted of a series of mental math questions and probability questions.

It was a very speedy process and you get relevant information about the role and questions prior to the interview. Offers occur on a rolling basis so I recommend applying early on in the recruitment round.
