Why do you want to find a mentor?
What is it you are hoping to achieve when you find a mentor? Is it to learn specific skills? Are you looking to secure a senior role like theirs in the future?
Whatever your reason, make sure you are clear about what it is you want to achieve, and write it down.
Having a clear mentoring objective will not only help you find the most suitable mentor, but ensure that the relationship – tasks you are assigned, regular meetings, networking events – all have that goal.
