T4 Automotive and self-driving XPeng Round 1

XPeng AI Infra first round

Real XPeng AI Infra first-round interview questions covering operator optimization

Operator optimization

Fundamentals

  1. Differences and underlying mechanisms of the four C++ cast types (static_cast, dynamic_cast, const_cast, reinterpret_cast).
  2. Dependency-order issues with dynamic libraries and how to resolve them.
  3. Read the given code and find 4 compile errors (focuses on const scope and constraints).

Operator optimization

  1. Read the given CUDA Kernel code and analyze what it does.

Project experience

  1. Deep project discussion.

Coding

  1. Compute the overlap area of two arbitrarily oriented rectangles in the plane (not axis-aligned).
