Crossover for Work PHP Software Engineer interview questions

The interview process took more than 4 months. YES, you read it right! After initial candidacy, that included CV and cover letter, I was "selected" to perform a real life test using Laravel. Even though I stated that I had no previous experience in that framework, I've managed to complete the small application (working) in the given deadline (about 3 days). Months passed without any response, then I got an invitation for an interview over Skype. Skype call was a personality and career assessment interview. Shortly after I got a confirmation that I would proceed to the next fase. Another month passed by, and I got a request for yet another interview, with some urgency. The interview was performed by someone that had not look at the performed assignment nor at my CV/Cover Letter, and was too busy drinking coffee(?) during the interview. Interview consisted of basic level (text-book) questions, with others that made no sense. Replied correctly to all of them, except one that I'll post below. Shortly after the interview, I've got a review in my e-mail, stating (among other things) that I could "improve on basic concepts". I didn't get an offer, based on my review, and the fact that I didn't provide a Wink video with my assignment, nor design diagrams nor RSS Feed (untrue), which all "affected negatively my overall score".

1. Test at hackerrank. Some of questions are good, some did not say anything about candidate except that he remember some documentation. First task is easy, second not so easy, but can be done. You should have some knowledge of algorithms and data structures. 2. Small project. It's not very complex, but the whole task is very complex itself. You should not only code it, but you code should have unit tests and pass it (at requirements they wrote that it should contain unit test, but in fact they see it's coverage). They also checks other code aspects: naming conventions, required techs used, modularity, etc...
