OA - 3 Design question and 2 Dsa questions, solved 1 on each , selected for interview Round 1 - adhoc process , questions about current work, resume projects, some questions about cs fundamentals,

I have applied to this company 3 times in last one year. First 2 times I was in college and they rejected my resume without any feedback. I applied again recently in February 2025. They sent me a test link. I could solve all 3 questions in the test. I called HR for feedback several times and one time she told she will let me know within a week and then whenever I called her she declined the call. After 15-20 days, I got rejection mail. Even worse experience happened with my friend but will tell that on some later day.
