I have a phone interview coming up. Is that mostly on SQL? What about the on-site interview? How much prob/stat vs SQL/Python vs Machine Learning vs Product Sense/fit? What counts more? Finally, I have a PhD in physics and an MS in math and a little more than 10 years experience in data analysis. If they decided to hire me, what would the level/comp be? E4? E5? Thank you.
Are you counting the PhD in your years of experience? If so then E4.
Actually 14 years on top of PhD.
Wow. Assuming you have solid skills and much of that experience is relevant (some places don't count non-DS experience) then you should be aiming for E5. Good luck!
Ask your recruiter what will be in interview. They can be surprisingly helpful.
