It was a hard process. I was first sent two Hackerrank questions which were fairly straightforward (hashmapping and some simple algebraic stuff). Then the behavioural online test was fine. Got invited to an online interview and was asked a fairly straightforward counting (hashmaps again) and sorting algorithms. Although I completed both the questions easily, I struggled on time complexity when asked and he asked me to name some more sorting algorithms and their time complexities (I couldn't remember any than the one I had used)! I didn't get an invite to the loop, but I wish they had provided some form of feedback after all the time I had invested to get to that stage.
