can someone share your experience and level of difficulty ?
When is your interview?
Mine is next week? What about yours ?
Same
How was the interview? can I DM you?
I would say advance SQL like on pgexercises.com and python is medium, string dict list set know what they do and write the methods out on a card if you don't know them. LC, Hacker rank and hackerearth for algorithm refreshing if you have been in data world along time would help you. I studdied both SQL and python each day for 2 weeks and passed 3 phone screens for DE with ease. Good luck!
Basic SQL and Python. Whatever they will ask is already available on Glassdoor.
