The process is 2 fold,
A type form that a person fills in the first round, has analytical, mathematical and such questions.
You are asked for your thoughts/ action plan for any project, topic and such acts.
If you clear the first round you sit for an interview with the senior team, including the Founder/Co-Founder.
Your previous education, marks etc dont matter to us. We only see how fit you are for the profile you applied for.
