I had four different rounds of video interview. It was all a quick process, the HR got back to me shortly after the interviews. The entire process took 3-4 weeks.

Phone interview for first two rounds followed up by a case for the final rounds. I would caution anyway who thinks Adobe being such a great company compensates for their terrible process of actually setting up and getting to the interviews, and to carefully review other reviews that talk about the issues they have run into. Lack of followup from multiple HR recruiters, interviewers not showing up on time, numerous last minute cancellations and changes (including a cancellation after 10pm the night before) are just a few of the issues I ran into. The interviews themselves were fairly standard and generally pleasant but it was certainly not worth the headache to get to that point for every single round, especially when there are so many other companies out there who have a pleasant experience from start to finish.
