EPAM Systems interview questions

I was having vary bad interview experience with EPAM. No management, No preocess. They called me 10 times for FF and when I attended Interview, they only asked me 1 question. Do you know Angular 6 and any live experience with Angular 6 ? And interview done. HR told me JD as Strong proficiency with JavaScript ECMAScript 5, 6, Reactjs, Angularjs, Requirements and specs analysis; Scrum events participation; Good understanding of web markup, including HTML5, CSS3 HR should understand the requirement before calling candidates. I skipped other companies interview calls and by travelling almost 25-30 km and invested 4 - 5 hours for this Interview. And they wasted my time and whole saturday. If company wants only Angular 6 people, so they should mention only that technology in the JD. And call only those candidates.
