Worst Interview Experience Ever!

I interviewed with the team in New York. I had a HackerRank interview which was of moderate difficulty. I cleared the technical phone screen and moved on to the HR round. The HR round was just about my interest in the company. They invited me for the onsite interview, and I provided dates and information to schedule it. However, after a few days, I was told that they had decided not to move forward with the onsite interview.

This is the worst feeling after everything I went through. I was really excited that I had a great onsite opportunity and now I feel very bad. I wish I had never applied for a job at Bloomberg!

I was not given a chance to prove myself after clearing the phone screen and HR rounds.
