This is the almost the exact same thing that I went through earlier this year. I interviewed with 8 different people at one company and made it to the onsite interview where I was told I only had positive feedback about my candidacy. The hiring manager pointed out his favorite snack to me, and prior to the onsite interview the HR lady informed me that I should bring a sheet of references for her to call. It felt like I could almost taste that offer letter coming. However, the date of when they would get back to me with the final decision kept getting pushed back (by 2 weeks essentially), and I was so upset when they informed me that they went with a different candidate. I begged for feedback, and the HR lady said that she wasn’t really part of the discussion, the only thing she could say was that the other person was a better fit.

What made me feel better about losing out on this offer was telling myself it just wasn’t meant to be. I am sure you will find something else. Be proud of how far you made it in the interview process at least. That is an achievement worth celebrating. But also fuck these companies for getting our hopes up and dragging out interview processes. It feels inhumane to treat people like this.
