Data Engineer interview at Bain & company

I have an upcoming interview at Bain and Company for their analytics division. They have an open position for Lead Data Engineer in India. What sort of questions are expected? I’ve read few glassdoor posts and mostly people have said to prepare for guesstimate questions and case studies. Not sure how relate that with data engineering.
