What are skills or experience that you must have before leaving banking?

Before leaving banking, it's crucial to have developed a strong set of skills and experiences. Here are a few that come to mind:

1. Sales Skills: In banking, you're not just crunching numbers. You're also a salesman. You need to understand how to present your story and what your clients or potential employers are looking for. This requires social intelligence to tell when they are disagreeing with you or aren't paying attention at all.

2. Self-Reflection: Reflect on your experiences in banking. What did you value the most? What sort of people did you enjoy working with? Your own reflections will give you the biggest insight about how you want to shape your future career.

3. Networking: If you're interested in finance as a career in the long term, then you should focus on networking extensively to get your name out there.

4. Client Service: Banking is a service-based industry. Your job is to serve and keep your clients happy. This skill applies at a deal level and at a career level.

5. Adaptability: Most people inside banks work on a number of desks and do a number of different roles. If you can anticipate the environment, you can keep the momentum in your career.

Remember, these skills and experiences are not just valuable in banking, but in many other industries as well. So, even if you're leaving banking, these skills will serve you well in your next venture.
