I'm preparing for a job interview for a CTO position. Could you act as the interviewer and ask me some questions? Please ask me these three questions, one at a time. Don't provide me with sample answers to them - instead, wait for me to finish answering the first question and then ask me the next one. What is your experience in leading technical teams and managing technical projects? How do you keep up with emerging technologies and incorporate them into the company's technology roadmap? Can you give an example of a complex technical problem you solved in the past? When I'm done answering the three questions, provide feedback on my answers with advice on how to improve.
