Priceline.com Full Stack JavaScript Developer interview questions

After a short conversation with Priceline's recruiter, two video call interviews were arranged at the next week. I'm a front end guys working on single page application in finance sector for several years. The first screening is on front end, of cause JavaScript. Questions cover ES6, promise, callback, bind, arrow function, etc. Then a small coding test through jsfiddle was taken - to go through an array of objects to sum a property's value. It looks easy, right? I think this will test your familiarity of ES6. In my working environment we're still using old JavaScript. Here you may need to use let, forEach, and arrow function. The second video interview took about 45 minutes, it is totally about Java. I didn't use Java for a few years, although work mostly with Java developers. Questions cover basic Java concepts, like OOP, interface vs abstract class, etc. Both interviewers are nice and professional. I didn't have other comments on them.
