PE interviews are notoriously rigorous and demanding, as they test your technical, behavioral, and case skills. You need to prepare well for each type of interview and anticipate the questions and scenarios you may face. For technical interviews, you need to master the fundamentals of accounting, finance, valuation, and deal structuring, as well as be able to build and explain financial models. For behavioral interviews, you need to show your motivation, fit, and personality, as well as answer common questions such as why PE, why this firm, and what are your strengths and weaknesses. For case interviews, you need to apply your consulting skills to PE-specific cases, such as investment thesis, market sizing, due diligence, and exit strategy. You also need to practice your presentation and communication skills, as well as your fit with the firm's culture and values.
