Palo Alto Networks Software Engineer(Internship) interview questions

Three phone interviews process took about 4 weeks. Had a 30 minute interview with a person from HR. Then in later weeks had two different 30 minute technical interviews over the phone with engineers.

I was interviewed for Software Intern - FrontEnd Team for Summer Intern 2018. Had three tech phone screens and a couple of calls with the recruiter. Process took almost 2 months. Round1: As this is for front end team a lot of questions are on javascript. Explain this in js, explain closures, explain bind, apply and call, and couple of coding questions based on setTimeouts. Round2: Event Bubbling and how do you stop it? Questions on scope. Class based Inheritance vs prototypal inheritance. Tricky coding questions on JS. Round 3: 2 questions on algos - better to do in JS. - Leetcode Easy level. Behavioral questions.
