I applied online and within 3 days received a hacker rank challenge. There were 7 questions. 3 programming & 4 MCQs. MCQs are focused on time complexity of sorting algorithms & output of pseudo code. The coding problems were Easy, Medium, Medium. You have to att empt the challenge within 3 days & 2 hours are provided. It was not tough but if you are not regularly coding (like me) then you can't crack it. I got a rejection in 3 days.
