This document provides guidance on preparing for common interview questions. It advises spending time preparing one's answers to expected questions about oneself, the company, previous roles and responsibilities, reasons for leaving past jobs, strengths and weaknesses, why one is a good fit, career goals, notice period, salary expectations, and achievements. Proper preparation is key as the initial 20 minute interview will largely determine whether one gets the job, and first impressions are important in making a positive impression on the interviewer.
