Need help with my machine coding round at Uber

hi all, I am a SDE2 with 2.5 years of experience. I recently got a call from uber and gave an OA. I have my interviews scheduled. I'm confident about DSA but worried about machine coding & LLD as this the first time I'm giving these rounds.

I got few doubts like can I give machine coding in python? Also are there any resources that I can checkout in the last minute which has previous year questions or anything?

I would be grateful if any one can help me out a little.

Thank you all for your time and patience!
