McKinsey Data Engineer

Hi everyone, hope I'm posting in the right place. I'm a college senior that applied for M's full-time data engineering role. I passed all test cases in the HackerRank, so I'm assuming I'm moving onto the next round. I've read that they don't give you a very long turnaround time, so I wanted to see if anyone had any insight as to what the next rounds will look like so I can start prepping -- are they cases? Leetcode style questions? Database questions? etc etc. Also, this is under "M Analytics," not "M Digital," so I'm assuming this isn't like a digital consultant role where I'd still do generalist projects, I'd only do data engineering. If I'm wrong, or if someone has some insight into the day-to-day work, I'd love to hear. Thanks so much!
