      Application

      I applied online. The process took 7 weeks. I interviewed at King (Barcelona) in Jul 2016

      Interview

      First visit was a face to face interview with two developers about what I know, what are my expectations, what is the job position about. Then I was given a test to complete at home by email. The test required to build a responsive JS app that displays a list of games (based on a provided json file) user can search the list, view details about each game on another page, add/remove game from favorites, view/search his favorites on another page. The requirements said that I was allowed to use js frameworks/libs but not too many (?). The resulting SPA was a Angular 1.5 + Bootstrap written in ES6 that had 3 views, routing, deep linking, pagination, search. For the app I used a basic angular seed with some modifications by me. On the second visit I had four interviews. First interview with two developers to review the test. They complained that I used too many libraries and my package.json is full of "libraries". In fact my app had only two dependencies: Angular and Bootstrap. The rest where clearly marked as "devDependencies" used for tool-ing (webpack modules, karma, linting, babel es6 transpiling modules...). Also they had the impression that I got everything from the seed. But my code was there and the app was performing as required. If I used a seed it doesn't mean the app was magically created from the seed or that I don't understand what is there. If I follow a JS pattern it doesn't mean I didn't write the code and everything comes from the pattern. In conclusion I think the description of the test was wrong and too loose. The interview also had some questions about Angular, some classic JS interview trick questions (e.g. what's the length of const x = [2]) and some fancy formulated questions about "CSS Paradigms" and another if the arrow function syntax uses "lexical scoping" for "this" asked after I already said in my own words that in arrow functions "this" is picked up from the surrounding function. Second interview was about "What if...", "What would you do..." Kanban/SCRUM/Agile questions. The person from the third interview didn't even read my CV, he asked "if they flew me in" but I actually live & work in Barcelona it's in the CV. Also he was arguing that ES6 has static type checking. (maybe it was a trick ?) The last interview... same boring questions all over again and some question about my work flow and my latest accomplishments. Most of his questions where based on the previous answer, and it felt like he was looking for a negative answer (Eg. Q: but why did you choose this framework when the previous app was written using that framework. A: Because it felt right for that specific project and in that context ) In the third and last visit I had two interviews. First it was with a developer that gave me some tests on a piece of paper using pseudo-code. At first I thought he's going to ask me more JS related questions. The questions where actually basic computer science questions about data structures, algorithms, big O complexity. Even if the questions were easy, the position was for a front end engineer that builds standard UI's not a back end developer, a game developer or a computer scientist... Anyway at least they didn't ask me to invert a binary tree on that paper because I would have just turned the page over. The second interview again about me, my work flow, "what would you do...", Agile, Scrum. After 7 interviews they said no and I lost two vacation days but I realized that maybe it's not the best place for me.
