Describe a good leader you know

I'll talk about a woman called Ha, who managed the small marketing team I joined straight out of university, my first proper job. She led a team of about eight people, mostly young and fairly inexperienced, myself included, in a company that honestly didn't have much structure at the time, so a lot of what the team became was really down to how she ran it. She treated people with a kind of directness I hadn't experienced from a boss before — she'd tell you clearly when something wasn't good enough, no vague hinting, but she'd do it privately and follow it up almost immediately with something specific you'd done well, so it never felt like an attack, more like she was actually invested in you improving rather than just correcting you for her own convenience. What makes her a good leader, I think, wasn't really about being liked, though people did like her, it was that she was consistently fair — she never seemed to have favourites, and when she took credit for the team's work in front of senior management, which she rarely did, she'd always specifically name whoever had actually done it rather than absorbing the praise herself. I've had other managers since who were more charismatic on the surface, more fun to be around day to day, but none who made me feel as genuinely capable as she did, which I think is probably the actual job of a leader.
