I worked at a company for 4 years. In the first 3.5, I was an individual contributor (IC). In the last 0.5 year I was 50% IC and 50% leading few junior ICs.
In my resume, I want to have two sections: one for work experience and one for leadership experience. For the former, when I list my IC role, is it OK to put 4 years for the date, and for the latter, put 0.5 years for the date? I am not sure if this may sound misleading as the dates for the two "positions" would be overlapping...
