"Overall my boss was very pleased with my performance. My last job was working retail, staying late and working early morning and late night shifts. I kept a positive attitude in stressful situations and worked well with my team. I learned a lot about how to give a customer the best experience, and I think my boss would say that's where I showed the most improvement."
The more specific you can get, the better! Take some time to reflect on your most recent role, mistakes you made and how you learned from them. Showing improvement in your performance reveals how teachable you are and that you can grow and adapt to new work environments. If you weren't consistent in your work, explain why. Your future employer will want someone who is reliable not just in showing up to work on time, but also in the way they treat customers and complete jobs.
