I was the better candidate. The other person has been unreliable. I have more experience, more qualifications, and have a lot more proof of what I have invested and achieved. I am baffled that they chose the other person. I don't want to go back in and face it all. This is such a huge set back and I am gutted at all the time and energy I invested in making sure I was ready for this role. No career progression for me now. Unsure what to do.
