Hi Abhishek, having previously worked in Business Intelligence I would assume you’re quite familiar with data and their business implications. This would definitely give you an edge whilst applying to places like the MBBs and the strategy arms of Big4s. I would suggest you to be structured in your approach while preparing for the case study and guesstimate rounds at these firms. You can check out Seekho’s consulting academy https://seekho.ai/academy/consulting, which focusses exactly on how you should go about your preparation in order to ace these interviews. Feel free to ask more questions in this thread.
