Have interviews coming up with FB, Uber and G. Anyone willing to help with a system design mock interview. Any other tips are also welcome.
Gainlo is good. A little expensive but worth it.
Have fb uber lined up. Hmu if you are interested
PracticeCodingInterview.com and Gainlo worked best for me.
Read company eng blogs. Binge read the companies you are interested in and design problems which seem relevant. https://github.com/kilimchoi/engineering-blogs Companies (in their tech blogs) often describe their engineering problems alongside their considerations and implmented solutions. Many blogs read like a tought process ... you should do something similar in an interview.
