A job was advertised internally without a person specification. I asked for the person specification and I received one after having had the interview. I didn’t get the job but a junior staff from my team got it. Looking at the person specification all shortlisted candidates did not meet at least 1 essential criterion. What is more, this junior person that I am still managing got the job and I can think about at least 3 more essential criteria that they didn’t meet. How is it possible? Shortlisting was done by my line manager, not HR. Would HR do anything about it? Readvertise the job? Thank you
