Is this fair?Watch
They never mentioned it before
This company they are all for diversity and equality, but how is fair??
I thought ever candidate starts at the same process, I don't get it
They didn't provide you with any useful feedback so there is nothing for you to reflect on. Keep applying elsewhere - you probably dodged a bullet.
It is fair that the employer decided to offer the job to another applicant.
Time to move on, apply for further jobs that meet your skillset range and pay expectations.
Good luck with your job hunting!
