I attended 3 rounds in total. I aced all the rounds with my best performance in both mathematics and coding. After 3 rounds there was a silence for a fortnight. I do not know what they did they expect beyond that but I got a reject at the end of it. I got a little pissed off and asked them the reason for which they told that there was no mistake with my performance but they found someone else who had more appropriate set of skills for their search.
