First 90 Days in New Role

I just landed a job in my new career field and want to make sure I succeed in the first 90 days. I'm especially nervous because I don't have traditional experience in this area.

Ask me about my new role, the company, my previous background, when I start, and what I'm most worried about. Also ask what I know about the role - who I report to, team size, key responsibilities. Then help me create:

1. A 30/60/90 day plan with specific goals for each phase
2. Critical relationships to build in the first few weeks
3. Quick wins I can achieve to build credibility fast
4. How to ask questions without looking incompetent
5. Skills I should prioritize learning on the job
6. How to leverage my unique background as a strength
7. Warning signs that things aren't going well
8. Strategies to manage imposter syndrome

I want to prove I belong here and validate that they made the right choice hiring me.
