Verification Questions: These questions will require you to provide objective information about yourself, such as your GPA, your major, the number of years you spent at your last job, etc. The interviewer may already know some of these answers, and is therefore simply checking the facts on your resume
Case Interview Questions: You will likely only encounter case interview questions if you are applying for a management consulting or investment banking position. In case interview questions, the employer gives the employee a business scenario and asks the interviewee how he would handle the situation. Sometimes these are questions about actual business situations, but other times, they are brain teasers that hold no direct relevance to the job ("How many gas stations are there in Europe?"). Case interview questions allow interviewees to demonstrate their analytical ability and problem solving skills.
Competency/Behavioral Questions: A behavioral question is one in which the interviewer asks you to describe a past situation when you demonstrated a particular quality. These questions indicate how you may handle similar situations at a new job. An example of a behavioral question is, "Describe the toughest challenge you faced at your last job. How did you handle it?
Situational Questions: A situational question is one in which the interviewer describes a hypothetical situation and the interviewee must explain how she would handle it or has handled it in the past. With this type of question, the interviewer wants to know how you will handle situations that may arise in the workplace. An example of a situational question is, "What would you do if two members of your team had a conflict that affected your productivity?"
