Even though I tend to perform generally well on interviews, I agree wholeheartedly with the arguments you make. Especially regarding interviews being a formality for many roles, when candidates are picked. This trend is very damaging for both the candidate and the organisation, as it wastes both parties' resources and shows that favoritism is seeded within the company's DNA.
I would like to add that in most cases, the complete lack of feedback after an interview - regardless whether it is successful or not is another aspect that is soul-crushing. As a concept, the way the interview process in many organisation is structured at present provides absolutely zero opportunity for personal growth for the applicant, while companies can often source ideas for their business development strategies from speaking with the individuals they interview.
Thanks for the opportunity to discuss and for the great article!
