Almost all job interviews will feature behavioral questions, in which applicants must talk about their experiences and skills. Some interviews, however, include other tests. For instance, those seeking consulting jobs must prepare for the case interview. Interviewers present aspiring consultants with a client dilemma and give them a time frame for coming up with a viable solution. Being unprepared, or failing to bring all your analytical skills to bear on the question, can quickly sink an applicant’s chances. But the biggest mistake applicants can make in a case interview is being indecisive, says Mark Howorth, senior director of global recruiting at the consulting firm Bain & Co. “Some people simply refuse to make a decision or keep changing their mind,” he says. “It’s a proxy of a real-world situation.” No one will hire a wishy-washy consultant, so provide a resolution.
