As a hiring manager I have learned that some people are trying to be deceptive that way and can thus no longer assume.

Thus I have to make sure either way and probe a lot unfortunately. Did they hold the title for the last 2 months and are jumping soon after? Will they do the same here? I want to know about and see the progression. There are situations where it is sort of irrelevant but in others it is detrimental if I have to probe.

If you are say in year 5 of your career and at senior level at just one company I want to know if you were a junior when hired out of college, were super awesome and made intermediate after one year and have been senior since year 2.5. You can show that to me right on the CV by listing it individually. If you just put the end title and that's it I will assume that you made senior this week and are trying to jump ship. This doesn't mean we can't figure it out together in the interview if it gets to that stage. But it sets a certain tone and connotation for the entire conversation. A bias to overcome.
