Hi there,
Welcome to PrepLounge and the wider consulting community! I can definitely relate to the challenges you're facing. When I started out, I grappled with similar issues, and they are common stumbling blocks in mastering case interviews. It can be helpful to work with a coach who has been in your shoes, but always great to get a foundation yourself. Here's what helped me improve in each of these areas:
1. Frameworks: Remember, the goal isn't to memorize frameworks but to understand the logic behind them. Try to understand why certain elements are included and how they interrelate. This way, you'll be better able to adapt them to the specific case at hand. Practicing a variety of cases can also help expose you to different frameworks and their applications.
2. Managing Information: This is indeed a common challenge in cases with many numbers. One approach that can help is to practice active listening and note-taking. Write down the key numbers and their units as they're mentioned. And don't hesitate to take a moment to organize your thoughts before diving into the analysis. Also, it can be useful to periodically summarize the information you've gathered, which helps reinforce understanding and identify gaps.
3. Chart Analysis: For chart analysis, it can be helpful to adopt a systematic approach. Start by understanding the chart's title, labels, and units. Then, look for trends, comparisons, and anomalies. Remember to interpret the data in the context of the case question, and don't rush. With time and practice, extracting key insights will become second nature.
I'd also add, don't be too hard on yourself. It's a learning curve, and with regular practice and feedback, you'll improve. If you ever need help or have any other questions, feel free to reach out. Many of us have been where you are and are more than willing to support your journey. Good luck with your preparations!
