It was simple and sweet. First, they replied via email with a link to a HackerRank test. Once I completed that, one of their technical team recruiters reached out for the second round of interview via Skype. I cracked that too by answering the questions asked and sharing my background.

Then, the next round was a one-hour interview with one of their frontend developers. It started well and ended well, but not quite. I answered every question asked, except one about the browser's fetch API, which I didn't know.

For the rest, they assigned me two problems, and I solved both. As we were running out of time, I shared what improvements could be made to the code instead of implementing them, and they said that was okay. I also described how to improve the algorithmic complexity of the code when asked.

They kept using 'awesome! awesome!' That's obviously a positive sign to hear during an interview.

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. I knew in the back of my mind that it could be avoided if we didn't need to wait for all promises to resolve or complete. If so, just wait for it and then process.

With this, they assumed I didn't know how Promise.all works. :(

I mean, seriously? Or was it that I couldn't say 'Yes' to the first question, 'Do you know about the browser's fetch API?'

I was really pissed off after hearing they didn't want to proceed further. The whole process wasted almost 5-10 hours of my time in total. I will never apply to Canva again for sure!

Do you know about the browser's fetch API?
