With a previous airline we had company SOPs for the bus and basically no checklist between After Start and Parking. No FMA calls except altitudes either. At one point there was a switch to pure OEM procedures which, no surprise, was not very welcome in the pilot community and a huge change for many. The silent cockpit philosophy worked very well, but relied on good training and an average experience of 7000+ hours for FOs and 15.000+ for captains. And yes, all in EASA country. Oh, why the switch to OEM? Simple, it's all about the money. Company SOPs in airbus FCOMs for over 30 slightly different equipment levels simply cost a huge amount of money to airbus to keep the FCOMs up to date.
