Hi Vera,
technical due diligence questions are not common in consulting interviews for generalist positions – usually what you need to know are just the common valuation techniques and related simplified formulas. However:
- You may get questions on your previous DD experiences
- You are supposed to know how basic DCF models work (eg the perpetuity formula)
- If your interviewer regularly works on due diligence and corporate finance and/or has M&A background, he/she may ask questions on technical topics so far that you have work experience related to that
Best,
Francesco
