I'll give you my LinkedIn profile to understand everything that you need to know about my career. There's obviously a lot more I've done in the past, but this has been my most recent work.

Analyze this and ask me 10 questions. Now, those questions shouldn't be like surface level. Go deeper, think about the kind of person I am, the kind of work I've done.

Ask me 10 deep and thought provoking questions that will make me reminisce, go back, and find times when I did something good at work or in life that was related to work. The end goal that I'm looking for is to create like a brag sheet for myself. I'm not good at bragging, so I need your help.

You need to ask me these questions, and then once I've given you the answers, you need to create that brag sheet for me in my own voice that if I wanted to, I could rehearse and speak out loud to feel good about my accomplishments.

And also if I show up to an interview, these should be actionable without being very boastful or putting anyo
