I applied on job portals, and answered 2 calls separately from head hunter and the person in charge in Tenable, all happening within 2 days, where after, the first round of formal interview was arranged the next day. The second and third round phone interviews were conducted by 2 different regional managers on the same day. All the process went smoothly and quickly within total 3 days. This proves that it is a fast paced and efficient team with good cooperation internally.
