They have a very unmanaged process.

The first round was Machine Coding, which was followed by a discussion.

After positive feedback from the first round, I had a round of Data Structures and Algorithms. After clearing this round, I was called the next weekend for further rounds.

The third round was a Design round. Then I had a Hiring Manager round. Everyone gave positive feedback.

However, they took four days after I cleared all the rounds to decide that I had not performed well.

It seems they are not just looking for good candidates but are searching for a needle in a haystack. If a candidate ditches them, they will blacklist and say whatever they want, but when these "baniya mind" companies do the same, they are not even capable of providing proper reasons for rejection.

One of my friends had a similar experience. I would not recommend wasting your precious time with them.
