It was a worst experience, initially they kept calling and bugging me to apply for the position, multiple people reached out to me, finally i thought I would give a try. First round: DS Algo - interviewer asked me to find kth smallest number - standard problem. I have answered it well as we know the best solution is to heaps and heapifycation, unfortunately the interviewer does Know anything about all these heaps, heapifying, heapsort array representation of heap. I tried my level best to explain him. But I felt like a waste of time.
