Last year I got an opportunity with McKinsey but I didn't make through the rounds. Now I have been presented with a new opportunity at BCG and they have sent me a link to a case interview prep course.
However, I do not have a background in business and I struggle with math. Although I work with a team to solve problems in my daily work, I am unsure how to structure, frame, and build hypotheses in different industries.
I am looking for advice on how to prepare especially in math from basics and for my first case practice and whether I should choose a case, practice it and then do it with a partner.
Any advice is appreciated since I am uncertain of what is the next step in term of preparation as they also did not inform me about interview date after the course invitation link.
