Have an onsite with Uber freight coming up. What can I expect? Leetcode style questions? Amazon style behavioral questions?
Is one of the coding interviews just OOP, like designing a card game or something
You mean system design? It depends on the interviewer, but apparently design a real-world system, such as the Uber mobile app itself.
The recruiter mentioned one of the interviews will be OOP class design, but maybe they meant something else.
Two coding stages, one architectural stage, one lunch stage, and one hiring manager stage. For prep, hope this can help: https://www.rooftopslushie.com/request/Uber-Freight---Backend-Software-Engineer-Interview-111
