Step one - phone screen with HR. (positive experience)
Step two - phone screen with direct manager. (positive experience)
Step three - in-person interview with 8 people over 4 hours. (neutral experience)
Kin Insurance's hiring process has some good things going on - HR was responsive, quick, and accommodating, which I appreciated, especially at a time when many companies unapologetically ghost candidates. I also appreciated that there was no project or homework during the process.
I personally think four hour interviews are too long. It is mutually beneficial for both candidates and team members for one to meet as many as possible during the interview process, but I would recommend maybe doing a panel format for 45 minutes with the 5-6 people who will not work most closely with this person instead of back-to-back 1:1s. I would recommend trimming the onsite interview process to 2-2.5 hours.
I will bring up one ironic point. Kin Insurance holds values that people enjoy being able to work autonomously, and that the person closest to a situation should be trusted to do the job. This drew me to the company. However, an 8 person/4 hour interview where people from all areas of the company ask grilling questions is the exact opposite of this. I do realize that leaving someone to work autonomously is not a viable interview process. However, as someone who is more introverted, I find these long, complex interviews to be exhausting. I think this process favors certain personality types and (please, please, please stay with me and hear me on this next point) that does not necessarily exactly correlate with who can perform the on-the-job skills. I personally struggle under the high-pressure questions and so do many other viable, strong-performing workers, and I think this might not be accounted for in this company's process.
Overall, I felt this was a fair process but I recommend some tweaks so it correlates with the company's core values.
