Splunk Data Visual Engineer interview questions

initial tech screen via codility - Finish a react component by making sure all the test cases pass - Implement something knowing Javascript Prototypes On-Site Coding Rounds (5 Tech screens, 1 Manager screen) They will ask general questions about the specific position you're applying for, but all of the white boarding is in JavaScript. I felt like I was interviewing to be part of the TC39 committee than actually applying for a Data Visual Engineer as they didn't test me on any d3 or react.
