Although the interviewer would like to know what they could be doing better, this is indeed not an invitation to do a deep dive into the things you do not like about JEA. Keep your answer firmly focused on what JEA is doing right. Offer a lighthearted suggestion for improvement. This suggestion could be mentioning a small change in their online job portal, or perhaps a stronger social media presence. Be sure to complete your answer on a positive note by complimenting JEA and affirming that you want to work for them.
"I understand that this industry is very competitive; however, I have always seen JEA as the industry leader. I enjoy how you relate to your customers through your marketing and branding efforts. It's all very relate-able content. If I could make one suggestion, I would comment on the user interface for your online job portal. I noticed that it isn't mobile friendly. With 67% of job seekers being mobile users, you would likely see a strong increase in applicants by making your job portal mobile friendly. Other than that, I like what I have experienced so far. I'm excited to have the opportunity to work at JEA!"
"JEA is doing so many things right, which is why I am so excited to be meeting with you today! I like the fact that your employees are so happy to work here. Your online reviews are solid. If I could make a suggestion, I would recommend a more robust website as so many customers are on mobile."
