i personally was in company for 6 months. developers had 10-15 years seniority. those processes happened without any connection to scrum, but. this company had mandated scrum that was defined by agile methodology department which developed it's own scrum tracking tools (i made sibling comment about it).

scum-sprints were used in order to avoid making designs and chop things into tiny pieces that were taking entire spring to develop. sprint demoes were "faked" (same demo could be shown for months at a time or there will be no real functionality behind it).

i worked in different company where they hired senior vp of engineering whose resume on linkedin was full of "implemented scrum - improved delivery/quality/etc". so engineering went to do hard core agile, with sprints, demoes that were showing amazing progress and that we are on track for doing everything in time. day before release eng. manager went to him and let him know that nothing works and they need at least half an year to get to half of the defined scope (i warned him about it two months ahead, he told me that I crazy). story ends with C-level appearing on one of the all-hands, calling him aside for a chat. he was never seen again.

so yes, for me, mandated scrum is symptom of the company that I won't go to work for.
