Experience of working in a team and dealing with people in a warehouse setting will improve your chances. Getting a forklift licence will be helpful. Having retail experience and experience of working in a supervisory role is also advantageous.

Try to get some vacation work or an industrial placement in a warehouse to test your suitability for this area of work. Consider a general warehouse position when starting out, for example, as a trainee supervisor with a smaller organisation. Experience in these jobs can lead to line-management positions.
