I had two interviews online. One of them was delayed in a week due to HR mistake in the calendar invite. The interviews were independent with a purpose to get to know me better as a person. The conversation went well, the interviewers were nice and interesting, but then I haven't received any emails for almost two weeks. Eventually I passed this stage, but during those two weeks of silence I've already accepted another offer and started working. Seems like a nice company, but I would suggest to improve your HR department performance and speed.
