Without a real-conditions simulation, you freeze in front of a Big 4 manager
Knowing the theory and performing under the pressure of an EY or Deloitte manager are two completely different things. Candidates who have never simulated an interview under real conditions — timing, follow-up questions, managing silence — systematically panic. Real-conditions training is the only way to eliminate this risk.
Key figure
