As with many answers you'll find in consulting, it depends.
Your consultant or manager will likely want to test the waters in order to gauge your personality, ability to learn, flexibility, and intellectual prowess, focusing on qualitative abilities before your quantitative abilities.
Generally, you can expect to spend a fair amount of time working in PowerPoint to refine slides to the style of your firm. You'll get a lot of feedback on how to tell a coherent, tight story. How you react and adapt to the feedback will lend toward executing on executing and effectively communicating findings from primary (conducting interviews) and secondary research (pulling data and other information). The last piece is often modeling or other quantitative analysis (forecasting, market sizing, etc.).
Again, it will largely depend on your firm and you as it relates to your case needs.
