BDO Manager, Strategy interview questions

I have my first round done in person. I took leave went all the way down. Post two days I received a call that I hv cleared first round and second one is case study. They have given me timeline. I have dedicated my time to it, prepared 12 slider case study with wo much sincerity and submitted it within timeline yet it has been two months not a single word from HR. They can’t reject u on basis of case study as o have been told I need to present it also but Idk wat happened but they haven’t replied and it’s been 2 months now
