Worst candidate experience ever! I went through 6 rounds of interviews spanning 4 months. This included HR, Hiring Manager, 1 Case Study round and various stakeholder interviews. After each of the initial 3 rounds they took 1 month to get back to me. Throughout the rounds whether during the case study or in some of the interviews they appreciated all my ideas on their active projects and in the final round they found my profile "not senior enough". The next week I find the same job reposted on LinkedIn with a higher level of experience required (which actually within their company represented an even higher position) vs when I had applied and finally 2 days after this I received a standard rejection email. What a pathetic way to treat a candidate. It seemed like a free idea generation exercise.
