Human Factors; Procedure
During climbout of ZZZ southbound just north of ZZZ1; ATC called out a Cessna 208 at our 12 o Clock and below us. We spotted the traffic and immediately after; a RA was triggered and it told us to monitor vertical speed. The traffic passed 400 feet below us and then we received a clear of conflict message. Flight continued uneventfully.Pilot of Cessna seemed to start a climb. ATC could have done a better job of keeping traffic separated.Always be vigilant of other traffic; especially on a VFR CAVU day.
CL-350 pilot reported an NMAC during departure climbout.  The conflicting aircraft was reported to be 400 feet below.
