Catherine Arnold, former managing director at Credit Suisse shares a story of her early days as a Wall Street analyst. She had vast experience and knowledge in the pharmaceutical industry and used it as an alternative path into the financial sector.

Although Catherine had never been an analyst before, she learned early on to never say no to a new opportunity. While she was eventually successful, it was a difficult route.
