Honesty really is the best policy when it comes to your career, and this maxim applies to writing a career objective, just as it does to your CV, job interview, conversations with colleagues and managers, right through to exit interviews. 

Being clear and honest about your ambitions is mutually beneficial for you and your prospective employer. Not only do you avoid potentially awkward conversations with future colleagues and employers, but by being honest employers know how to make roles better suited for you, including offering more tailored learning and development opportunities and getting you the most suitable mentor.
