The open office environment fosters collaboration and creativity among peers. The casual atmosphere is professional yet fun to work at. Yes, management could be improved, as you are often left without guidance or typical performance reviews. This can be difficult for some, but as long as you are self-motivated to keep moving forward and improving, it's a non-issue. This is a small company that operates at times like a startup... you have to be flexible and understand the startup-like "everyone has to chip in to get stuff done" mentality, and be comfortable with that. I personally wouldn't have it any other way.
I've been at Prontoforms for 2 years, and despite being constantly recruited by the so-called "top companies" (i.e. Shopify, You i, etc), there is no way I'm leaving.
Regular communication from most teams (with lunches), great snack bar, open workspace, startup feel
Lack of HR processes (talent management)
