This question already has an answer here:
On my resume, how would I go about displaying that I held multiple titles at the same institution?
Some examples of what I'm talking about:
- In university, I was a computer lab supervisor (hiring/firing students to staff a lab and create the weekly schedules, address performance, etc), a peer tutor (working independently helping students with CS classes underneath a distant manager), and I worked at the IT service desk (on-site classroom tech support, then got a promotion after a year), all at the same time. All different titles/responsibilities/reporting managers, but all at the same company (my college).
- After college, I got hired on somewhere else as a Dev, was promoted to Senior Developer, all at the same position/department/company
- In the same company as 2, but did a lateral move to a different department with radically different responsibilities & technologies (Oracle packaged app production support vs full stack web developer doing long-term build/project work), but technically the same title of Sr Dev and same company as 2
