The interview process is a multi-stage evaluation to determine a candidate's fit for a job, typically involving screening calls, interviews, and assessments, and ending with a background check and job offer. It usually follows a structure of introductions, an exchange of questions and answers, and a conclusion, and may involve multiple interviewers using various methods like behavioral or competency-based questions. The process is a two-way street where both the employer assesses the candidate and the candidate evaluates the company.
