The hiring model has remained largely unchanged for decades. Generally, candidates submit a CV, get called into either a group interview or a 1-2-1 chat with a recruiter or hiring manager and get asked questions, for which they’ve probably rehearsed answers and considered exactly how they want to portray themselves.
Many stick to this model because, simply, it works. One way or another, the job post gets filled, hopefully with a professional who is hard-working and dedicated, and that’s the end of the story until that person either leaves for another position, or the position is made redundant. In which case, it either starts again, or it doesn’t.
