I had 3 interviews and then an offer. The first interview was just a vetting call. The second was a HireVue coding interview for 2 hours. There were 2 questions, neither very difficult, but the IDE is atrocious. You can in fact use a personal IDE and then paste the code in the online IDE afterward. Assuming you get at least one correct, you will likely move on.

Then I got a call from the recruiter, and they scheduled a 3rd Skype interview. It was 2 hours: 1 hour behavioral and 1 hour technical (resume questions mostly).

Don't BS; just admit if you don't know.

Tell me a time that you had to deliver under stress.

Tell me a time when you had conflict on your team, and how you handled it?

Tell me a time when you failed to deliver.

If a bug exists, what is the process you would do to solve it?
