How can I effectively prepare for incremental, real-world-style coding interviews—like those at Reddit or Stripe—that go beyond typical LeetCode problems? I'm specifically looking to understand how to tackle layered, evolving problems that simulate real world scenarios rather than algorithmic problems.
I just build side projects: https://www.jointaro.com/course/ace-your-tech-interview-and-get-a-job-as-a-software-engineer/practical-coding/
There are other types of practical coding rounds though like debugging, reviewing a pull request, adding unit tests, etc. For these rounds you should try to get a good read from the recruiter, and tune your studying from there.
In a vacuum, I practice for companies that do these types of interviews by building pieces of their product. Stripe is very tricky, but I would practice for Reddit by trying to rebuild their home feed using their API for example (unless the recruiter told me otherwise).
