Avoid duplicating applications unless the firm or recruiter explicitly encourages it. If your level is genuinely ambiguous, a short recruiter conversation is usually cleaner than applying to multiple levels independently.

Seniority decisions depend on the relevance and depth of your experience, not only years worked. Two candidates with the same tenure can enter at different levels based on leadership, client exposure, and role scope.

Apply to the level that best matches the job description and your strongest evidence. In many experienced-hire processes, recruiting can recalibrate the level if they think another entry point fits better.

If you have a contact in recruiting, ask the level question directly before submitting duplicates. The experienced-hire consulting guide can help you frame the experience-to-level discussion.

I would ask recruiting rather than send two nearly identical applications.
