“As a fairly new employee, I must say that Colt is like a roller coaster. It is fast paced and thrilling, sometimes it makes you want to scream with excitement or hold your breath before the next turn, but one thing is certain – at the end of the day, you can’t wait for the next ride! One aspect which has made my experience with Colt really positive is the smart and motivated people working here.”Careers at Colt
