First you will get Data Interview Problem that you have to answer (I was given one week to finish). After that you will have an interview with user, they might mention your previous answer to the Problem and would move on with basic background check according to your CV and ask some things regarding what you tell them. Then you would have the next interview with another user. They would do the CV check again and ask you things according to your telling again.

First I got contacted by the HR person which described what the company is doing and how the recruitment process works. Afterwards, they sent me a programming and maths assignment with several questions which had to be done within 3 days(they are flexible about the date though, so if your busy you can ask them to sent it a week later) and finally a technical interview with 2 Data Scientists.
