It goes without saying that it is mandatory for everyone to meet their deadlines and to be punctual. There is no hierarchy whatsoever and everyone is open and receptive to feedback and constructive criticism. What keeps us motivated and driven is our vision for CODfirm. It does get stressful at times, just like it would at any fast-growing startup with a grand vision. In a sentence, it is a fun yet challenging work environment.
