I applied online.

Earlier stages were well-organized and recruiter communication was fine. The technical round was disappointing.

The interviewer was visibly working on a second screen for much of the session and clearly wasn't following the conversation - at one point he asked me a question I had already answered a few minutes earlier, as if he hadn't heard the first response. Follow-ups repeatedly circled back to points I'd already addressed.

For a principal-level loop I expected a rigorous, two-way technical discussion. It's hard to get a fair evaluation when the interviewer isn't actually present for it.
