Pros
HSBC provides great opportunities for learning, training and personal development. They have extensive on-line training, special training centers and provide a great tuition reimbursement package. Depending o the department, you may also be able to help the business grow - management actually listens to feedback from their staff. Direct manager should hold weekly or bi-weekly one-on-one sessions with their staff to discuss any issues and keep communication open.
Cons
Communication from management isn't always as clear and timely as it should be. You will likely spend a portion of your time putting out fires that could have been prevented with timely communication from the management team. Semi-annual and annual reviews could use improvement - they are often done in a vacuum by manager without employee input.
