After going through an exhaustive interview process with five rounds, including discussions with the direct manager, HR, group manager, and CTO, I was confident that I was a strong fit for the role. Every interviewer expressed their approval, with the CTO being the final decision-maker. When he ultimately said 'no,' I was left bewildered. They mentioned that they weren't sure but liked my personality, yet no one was willing to be the one to make the final call. It felt like my time and energy had been wasted, as I had invested significant effort into the process only to be let down in the end.
