It was simple and sweet. First, they've replied via email with a link to HeackerRank test. Once I have completed that, one of their technical team recruiters reached for the second round of interview via Skype. I have been able to crack that too by answering the questions I was asked and sharing the background. Then the next round was one hour interview with one of their frontend developers. It started well and ended well too, but not really. Whatever the questions I was asked, I answered except one that I didn't know about the browser' fetch API. Rest, he assigned me two problems and I solved both of them. As we were running out of time so I shared what improvements could have been in the code instead of implementing them and he said that's okay. Also described how we can improve the algorithmic complexity of the code when he asked. And he kept using, 'awesome! awesome!' That's obviously a positive sign when you hear it from an interview. So next, here's where the magic happened: I used Promise.all in the second problem to wait for an iterator of promises to complete and then process the result. And I knew in my back of my mind that it can be avoided if we do not need to wait whether all promises are resolved or completed. If so then just wait for it and then process. With this, he assumed that I do not know how Promise.all work. :( I mean seriously? Or it was that I could not say, 'Yes' to the first question, 'you know about the browser' fetch API?' I was really pissed-off after hearing that they do not want to proceed further. The whole process wasted almost 5-10 hours of my time in total. I will never apply back at Canva for sure!
