The interview process had three primary stages; the application survey, the one-way video interview with predetermined questions and a telephone interview with an HR representative.
The survey is in-depth, easy and kind of enjoyable (If that's even possible). Just make sure to only answer with definitive answers on the "true or untrue" spectrum. Do not be wishy-washy.
Secondly, the video interview is nice in the sense of being able to control the flow of your answers. You have the time to review your thoughts, and look back onto the videos you'll be submitting. The interview is conducted through a thrid-party app, SparkHire. You have unlimited re-tries, so there's no excuse for a less than perfect answer!
Lastly, there was an in-depth, lengthy telephone interview. The HR representative I was working with called herself and conducted it. It can get to be 45 minutes to an hour long as a whole, so be sure to give yourself enough time to speak, and give yourself a nice, quiet area to work in.
Overall, I was thoroughly impressed with the depth and detail put into the interview process, given you have no actual face-time with anybody! 9/10, would totally sell myself again to them!
