Interviews are chances for candidates to demonstrate their communication skills. Sometimes interviewers ask coding questions with new concepts to verify candidates’ learning skills. Candidates might solve new interview problems with skills that reapply solutions to classic problems or solve problems abstracted from daily life and work with mathematical modeling skills. Divergent thinking skills are necessary for candidates when conventional solutions are disallowed by interviewers. All of these skills are discussed in detail with several sample coding interview questions in this chapter.
