Old tech trying to look cool...
Pros
They pay decent, and there are lot of smart engineers.
Cons
Old news, seniority is based on time there, not skill, and has a clear good-ol-boys-and-girls-club... not a good feeling for most new hires because you quickly realize you have to fit into the 'click' to ever make it there. No millennial or younger will choose Splunk if they are searching for tool like this - so they are bound to die out. Open source stacks with datadog for example are eating Splunk's justification of being a closed-garden product and business, and old money (huuuge banks, VCs, etc) will never let them start to open source. They were in the process of changing both their product, as well as their form of revenue (cloud instead of local install) and the CTO up and left... not a good sign when the CEO is telling everyone this is going to be huge for us, etc. A couple months after I jumped I read that the CEO moved on too... not a good signal.
