Prior to going into teaching, I was a senior IT Manager. I had run quite a few recruitment drives. Advertised vacancies to replace staff who had left. Read thousands of application letters and their accompanying CVs. I invited the best candidates, on paper, for an interview. I then chose the best candidate(s) to fill the vacancy(ies). I didn't give a rat's ass if they were male, female, Caucasian, BAME or whatever. I was purely interested in a) their suitability to perform the job to the levels I and the company required and b) whether they fit into the team. To help with that, part of the interview was conducted with members of the team present and taking an active part.
As a result we ended up with a broad spread of characters, introvert, extrovert, thinkers, doers............ and a spread of gender, colour etc.
If I'd ended up with a department of black, lesbian, catholic invalids I would be happy in the knowledge that I had hired the best available candidate at the time of hiring. I know for a fact that my gaffer wanted me to hire the best available. That was my job and that was what I did. I am actually amazed that others don't do the same.
After retiring from teaching I did 2 days a week for 2 years working at a friend's IT recruitment company vetting application letters, CVs, doing first interviews and running the best candidates past the client before deciding who would be invited for interview. Again, I was only interested in how good they were for the job in hand. The final decision was the client's but I gave them the best of the applicants to choose from. That approach saw us (a small company of 5 people) take some clients off large national and multinational agencies. We had the personal touch and the clients were happy with what we sent them. To cut down on staff, the larger companies vetted CVs by passing the CVs through software looking for keywords. Their agents had no IT background and couldn't understand the CVs if they tried. We were all IT professionals and we knew if someone was trying to pull the wool over our eyes. One time I had a CV that looked perfect for the job. I then studied it and the applicant was claiming to have used some products but could show no evidence of where he had learned how to use/code it. I invited him for a "1st interview". For 20 minutes he had the idea it was going well and I was "buying" his very well rehearsed backstory. I then asked a few hard but fair questions regarding where he'd had, for instance, the training for CICS and a couple of technical questions. He was stymied. If I'd sent him to the client, I am 99% certain they would have hired him and that would have damaged our reputation.
Why hire 2nd or 3rd best just because they fit a certain demographic? Best for the job has always been my mantra.
