I am a Python/Django guy and have worked in organizations where it is used extensively. I did complete the challenge successfully. After successful completion of the coding challenge, had an HR call. I was told by HR that I would be getting information about next rounds in few days. And bam! a reject! That too without any feedback(even though I asked for it) I know the product is awesome, and you guys are doing a great job; but I was a bit disappointed for not getting the reason of reject.
