Front End Software Engineer Interview Questions
852 front end software engineer interview questions shared by candidates
Out of the 42 multiple choice questions, I could probably count on one hand the ones that I felt were relevant to me as a front end engineer. There were many questions in C and Java on topics I haven't thought about since college, and additionally there were questions in Ruby and Python that I just couldn't answer because I don't know those languages. Other questions involved scenarios that on a job, I would ask either my dev ops person or a back end person.

The coding exercise consisted of creating a JavaScript class called Model that would expose the following methods: get, set, has, on, trigger. The class signature would be something like the following: const Woof = new Model({id:133, type: 'dog', name:'Spot' }); The has method would take a property name and check if the model has that particular property, return true or false. The get method would take a property name and return it's value if it exists. Return null if not. The set method would take a property name and a value and set that property's value if the property exists. The on method would allow for the addition of an event to the class and a callback function. The trigger method would allow the "triggering" of a particular event and pass any number of parameters to the callback function. You can use ES5 or ES6 syntax.
