I had a phone interview a couple weeks ago with an HR recruiter for a graphic design position. A week later had a face to face interview with the senior designer. After the interview, she said they were asking candidates to complete two design projects to test for skill and design style. She told me to take the weekend to complete the projects and return by Tuesday. I worked on both projects all weekend, putting in a huge amount of effort.
Woke up to an email Monday morning from the HR recruiter saying they chose a final candidate for the position. I sent an email back to both of them stating my disappointment and letting them know how much time I spent on the project to have it wasted in such a manner. It wasn't a mean email, just forthright and very expressive of disappointment about my time.
The HR recruiter wrote me back and said they made a mistake and there was miscommunication, and that they would review my work. Now I feel so ashamed that I wrote that email. It's confusing because they said they had a final candidate. Should I have handled it differently?
