Applied through career talk, after phone screen with HR, there were 2 assessment days. One for individual and one for group assessment.
For the individual assessment day, there was a case study to extract information from couple tables, was not particularly difficult. Then there was a technical test which did not include any live coding, there were all mcs to choose which code was the right one.
For the group assessment day, first there is a networking session with current employee, be sure to ask some meaningful questions. Then there is a individual test on improving data pipeline. Finally, there was a group discussion/debate based on some given data, be sure to use the data given to make strong arguments.
