GraphQL Interview Workbook: 128 Questions with Model Answers, Follow-ups and Drills
The only GraphQL workbook you will need.
GraphQL interviews don't stop at the definition. The interviewer asks a follow-up, then asks you to tie it to something you've built. This workbook prepares you for all three.
