I had two interviews with a positive experience and a rejection with a negative experience. The first one was with an HR person, which asked me some basic questions about me and explained what is Power Diary and what is their product/service. The second one was with the tech manager, which asked me more or less the same questions but some technical questions as well. By the end of it, I I received a code challenge by email. One week after I sent my solution for the code challenge, I received a generic email saying that "the decision has been made to proceed with other candidates who better suit our organisational requirements" - even though I thought the interviews went very well and that my solution to the code challenge had high quality. I'd like to have received a more specific feedback on why they rejected my application, explaining me what I could improve in order to meet their criteria, specially after I invested time on it.
