Very lengthy interview process, had 6 rounds in total, invested too much time cleared all rounds till round 5, submitted test project on time and then the HR said we will do one last round, and boom nothing after that. Didnot hear anything from the HR, isn't it basic to inform the person who has invested so much of their time and it is fine if you want to reject them but give a reason/ feedback. Glad I did not join such an unprofessional company
