It wasn't bad. The interview evaluates your product thinking skills for the most part. But they also want to know more about your problem-solving skills. Some of the questions included: How would you improve user engagement on WhatsApp? Tell me a time when you influenced engineering to build a particular feature. Design a new feature for Twitter that improves the new user’s experience

It was a long process—about 4 interviews (1 with the hiring manager, 1 with potential teammates, final 2-part panel with various people from product, research, engineering, and design) over the span of 5 months. After being told I was a "yes" from everyone and the recruiter claiming she had enough info to put together an offer, I was unfortunately ghosted under the guise of them "finding a better team" for me. I did have one more interview with a different hiring manager for another team, but my emails to them since then were met with silence. This was a very disillusioning and heartbreaking experience for me so I likely will not apply to Twitter again.
