Look, we both know you have like… eight other Medium articles open in other tabs right now and you’re eager to get to them. If you’re here for practical advice or sheer curiosity, I’ll give you a list of titles to look for. All of them nice and bold, just like us skimmers like it.

To me, it was mind-blowing. I had little actual experience building real-world applications, but I achieved it for a very simple reason.

I assure you this is not clickbait…

It’s pretty common for companies to flat out reject your application without giving you a hint on their decision. This time, however, I got feedback for real.

As a fairly new developer, coming from a non-technical background, my learning curve has been very steep.

I was once rejected in a selection process after handing over a technical test. I was asked to create a full-stack application that read a list of 25 sales records and returned a filterable, paginated table (six records at a time).
