Pros
BMC provided training! From day one you'll be required to pass and maintain certifications. Column will pay for all of these trainings, as long as you fulfill a two year contract with them. I doubt these trainings cost Column anything since they are BMC's global partner. Once you've received your certifications and customers are happy with your work, you'll have no trouble finding better employment and more compensation elsewhere.
Cons
Management is psychotic! Team leads and upper management do not lead or manage, they shout, berate and belittle employees on a daily basis. Although your customers will love and appreciate your hard work, Column will attempt to minimize your role and take recognition for your work. Once you leave the company you open yourself to a litany of backstabbing and attempts to defile your character. Trust is not a word that is used at Column. You'll definitely need antidepressants if you stay with this company too long.
