StashFin Software Developer interview questions

Recruiter contacted me and scheduled an interview. There were two coding rounds post that with the interviewers. The first coding round was cleared and next round was scheduled. The questions asked in the next round were answered in the required time complexity. The interview ended on a happy note. Then I received another call from their HR to schedule the second round which was already been taken so I iterated her the same. My job application was finally rejected without giving any clue or feedback on what went wrong even after asking them multiple times over email.

They have 1 week interview process, in which they have hr round then technical interview and again hr round after that they will send you the confirmation over mail.
