This was a long interview process over about six weeks, with six rounds. It started with the standard HR pre-screening, followed by a fairly extensive technical project, then another four rounds of on-line interviews. Kairos was very good with communications, never leaving me in the dark or wondering where the process was. Everyone was pleasant to deal with and have an obvious love for the work they do. Questions were typically applicable to the work entailed as opposed to generic personality scripts. The work was well explained to me and I felt like I had a much better understanding of the company than I've had with any previous interview. But I will say that a process of this long makes it a bit more of an emotional investment than a more normal one or two interview process. So it does have a bit more impact if you aren't the one chosen, but I'd happily apply again.
