To prepare for a programming interview, begin by studying common interview concepts and working through practice interview questions. Once you land a job, your responsibilities revolve around solving large, complex problems over weeks or even months. However, in your job interviews, your interviewers will ask you to solve small problems in less than an hour—and they’ll expect you to explain your thought process clearly in real-time as you problem-solve. Programming interview questions often emphasize algorithms and data structures, so hone your skills in solving those types of problems before your interview. Enthusiasm and strong communication skills go a long way.
