Here's a secret: nobody really cares what your job title is. As Vietnhi's already mentioned, what matters is what you do in your role. The only bits where your current title has value:
- Getting past the initial check when you're applying for a new role. In this case, make sure whatever title is on your resume is whatever you think has the best chance of getting whoever's doing the initial resume scan to read the rest of it - and crucially, this may vary depending on the role you're applying for.
- Ensuring that you pass any background checks. Again as noted by Vietnhi, the difference between "consultant" and "analyst" is pretty small, but if you're really worried about it you can always do something like "X Analyst (official title: X Consultant)".
