eBay Senior Software Engineer - Front End Engineer interview questions

Got an interview invite after applying online. 1. Coding interview - your basic React app development, custom dropdowns and API integration 2. Coding interview - another React app, a custom accordion with dummy data 3. Coding interview - a string manipulation with JS. The poor network connection during this interview affected my output and they unfairly used this against me. 4. They said it was supposed to be a managerial/leadership interview but it ended up as a sort of system design. It wasn’t clear what the interviewer wanted for the requirements because it kept changing with each question. I like to add the interviewer had poor grasp of English because I had to dumb down whatever I said. 5. Again another system design but it was from backend like setting cache on server. Then they asked about real time communication on apps. I don’t know why these people thought I would be an expertise on it. Anyway, the interview seemed totally unfair especially to the end. The questions were vague and taken from topics that wasn’t part of the JD.
