Having worked at Plus for 3 years I have recommended to several friends at other firms who have joined Plus. Mentoring, 9 day fortnight, and great culture. Young supportive team. Good Design.
Cons
Analogue systems could be improved - lots of QA that feels overdone.
-Directors are great - really encouraging / friendly.
-Cohesive working environment, team effort.
-Interesting projects across variety of scales.
-Variety of experience
Cons
Small office so career progression might be lesser than a larger firm.
