Had a very bad experience interviewing at Coinswitch

1st round of Interview was DSA. 2 medium leetcode questions were asked.

1. https://leetcode.com/problems/non-overlapping-intervals/description/
2. https://leetcode.com/problems/course-schedule/description/

I was able to solve and run both the problems. Rest of the interview were scheduled for the same day so I got my other company interviews rescheduled to further days but then recruiter sends a mail after the Round1 - "Thanks for applying, we are moving forward with other candidate".
When I asked for proper feedback they ghosted me.

It has been a worst experience.
