Very thorough. Several qualifying phone calls with both CrossBorder's team as well as the recruiting firm they used, Pareto Law, before an "Assessment Day" that was 8:30am - 4:00 pm (although realistically I was finished by ~2pm). The Assessment Day was virtual and consisted of several team activities, an elevator pitch, etc; while this was lengthy and sounds tedious, I was very thoroughly prepared by the recruiters and previous phone-interviews as to what I should expect, what I should prepare, etc. Overall, it was a more tedious process than I was used to, but was happy with it and thankful they were so thorough as my previous employer- it made me feel they truly interested, truly were willing to invest in the employees they did choose, and that if I did receive an offer (which I did) that I was truly qualified for the job and would be successful in it.
