In the first screening call the HR told me to complete the assignment in 2 Days. I gave my best and have done even more than what i was asked to do in the assignment scope. I completed the assignment along with my day job within the given time duration. Post I submitted the assignment, the HR stopped replying to my mails. I don't know how come this big of a company hire such non empathetic and unresponsive HRs. If they tell you to complete the assignment first, then be prepared to hear nothing from them post submission.
