Not stressful, they were very laid back and just wanted to know if I was qualified for the position or not. Two people interviewed at once and it was not a bad experience at all. I loved the process. Two interviews

1st phase screening; went pretty well. HR booked video call for technical interview right away. 2nd phase - video call with 2 engineers. I planned on purpose to be out the office for that call, but nobody joined from Ultimate Software within 20 min. HR didn't answer email and phone while I was waiting on the call. No any explanation/feedback followed after that. Quite disappointed with such disrespect of candidate's time Update: HR came back after few days (after 1st version of this review was published) saying this position is not anymore available because of a merger with Kronos. Said she will comeback within 24 hours with other opportunity, since they liked my CV. As you might guess - nothing for 2 weeks since then. No judging, merger is a big thing.
