Mendix Frontend Developer interview questions

Did a interview with their on HR, the guys kept me update and offer for help multiple times. After that I did a interview with two managers, no technical stuff just work experiece questions. After that the test, It was supposed to take 4 hours but I'm pretty sure it would be impossible to be done. You need to solve some bugs and add functionalities to a codebase they provide, the tasks are not detailed so assume they expect more than they are telling you. They provide a very usefull feedback!
