I have contacted by HR and asked me to take Hacker earth test. Attempted all three questions. Out of three , one was not passed all test cases. Got short listed for next round. Probably they would have urgent requirement. Back to back i have gone through two technical rounds. They short listed me to next round which is director round where behavioural questions asked and about hacker earth test. Director asked me to rewrite the third program which satisfies all test cases. I did it. Though it was scheduled for 1 hour. He extended my interview 30 more minutes. I did not hear anything from HR thereafter.
