Pros
They do pay well and have good benefits.
Kontras
Altium overstates their fantastic company culture and 'Guiding Principles'
In fact, the real company culture is quite the opposite of what is projected. There are great people at the company that do great work. Unfortunately, those principles are not followed if it comes at any cost or conflict with operations. Many great, long term employees have recently left due to the new company direction under the new CEO.
