eBay interview questions

One online assessment that lasts about an hour with 5 questions on the easy side. Then two rounds of video interview that asked a lot of CS topics including OOP, cache, concurrency etc. I missed only 1-2 small questions but didn’t get offer. I think it’s definitely too hard for an intern interview.

7-8 rounds with individuals. No formal process, each interview was very different. No heads up from HR how to prepare or what style they would be. Most were very informal.
