eBay Software Engineer III interview questions

I applied online, meet with a recruiter within a week, went through a leetcode round then the 5 hour final round consisting of system design, code refactoring, algorithm round and hiring manager. Honestly the most bipolar interview experience I've had, some of the interviewers you can tell are passionate about their job and the work, and on the other hand one interviewer used the interview as an extended lunch hour. focusing more on a subway footlong than me.

The recruiter informed me that there would be a 1-hour screening round before progressing to five additional 1-hour rounds. The interviewer arrived nearly 10 minutes late and spent the first 20 minutes reviewing my recent architectural contributions on a virtual whiteboard. With 30 minutes left, they shifted to coding, which was more complex than expected, involving a lengthy object-oriented code task that typically requires over an hour to solve. Poor time management and structure were evident, and I only learned in the final minutes that they’d assigned the wrong interviewer for my level. Additionally, despite encouraging an expedited interview, they initially scheduled me and then rescheduled to a later slot, reflecting unprofessional planning on eBay’s and/or the recruiter's part.
