IBM Consulting Case Interview Tips
Here are six of the best things you can do to get ready for an interview with IBM Consulting or IBM Global Business Services
Tip #1: Start preparing early
Mastering case interviews takes time. You can’t learn all the skills and tricks you need to do well in case interviews in one day or one week. Start getting ready for your case interviews at least one or two months ahead of time to give yourself time to learn and practice.
Tip #2: Practice with a case partner
Practicing case interviews with a partner is the best way to simulate a real case interview. If you do mock cases by yourself, you won’t be able to work on many things that are important for case interviews. Casing with a partner lets you practice your communication, presentation, and collaboration skills.
Tip #3: Keep a list of feedback from each case
While you’re practicing, you should write down all the different things your case interview partner tells you. This way, you’ll be able to identify trends and prioritize what improvement areas to focus on. For instance, if you keep getting feedback in each practice case that your answers need to be more structured, that should be the first thing you work on.
Tip #4: Focus on improving one thing at a time
After doing some practice case interviews, you’ll likely have a long list of feedback and improvement areas. Try to focus on improving one thing at a time. Before each practice case, decide on the one thing that you really want to focus on and nail. This will be much more effective than trying to improve everything at once.
Tip #5: Use a hypothesis-driven approach
During the case interview, you should have a hypothesis of what the answer to the case is. A hypothesis is simply an educated guess based on the knowledge that you have. As you analyze data and gather more information, make sure to be constantly changing and refining your hypothesis.
There are two benefits to using a hypothesis to drive the direction of the case. One, it makes sure you’re focusing on the right things that will help you solve or answer the case. Two, you will already have a good idea of what the answer or solution to the case should be by the time the interviewer asks you for your opinion.
Tip #6: Be 80/20
You have limited time during a case interview to solve the case. Because of this, you won’t be able to cover all the different parts of your framework and get answers to all of your questions. Therefore, focus on the most important issues and use the 80/20 principle.
The 80/20 principle states that 80% of the outcome comes from 20% of your effort. Focus on the most important questions or areas that will have the most effect on how you come up with your answer or suggestion during a case interview.
