:exclamation:  Some questions are more for testing your own knowledge than actual valid interview questions :page_facing_up:  Different interviewers focus on different things. Some will focus on your resume while others might focus on scenario questions or specific technical questions. In this repository I tried to cover different types of questions for you to practice and test your knowledge
:exclamation:  For interviewers, I suggest focusing on 3 things: the resume of the candidate, scenario questions and technical concepts. Don't have an interview of only specific technical questions
