Oracle Sneior Software Engineer interview questions

One hour technical/coding interview. Honestly pretty easy question to answer about hierarchy in java. After that was the loop(1 coding question, 1 coding question about data structures, a bartender who was a culture check and a design question. Which was a hectic mess. One of the people who were supposed to interview showed up 20 mins late. The other one was asking questions but wording them weirdly so it was hard to figure out what they wanted exactly. The other two though were great and no problems with the process. For a big company you think they would have their hiring process figured out but that obviously do not. I was even sent the wrong order on what people were going to be interviewing me on. One of them even did the wrong interview part and didn't notice until half way through.
