Pros
Can get good engineering experience with the right team, teams are largely shielded from the chaos in middle to upper management and resulting from M&A. Benefits/comp seem average. Many people are nice and amenable. There are no pros for non-engineering, professional staff other than the paycheck.
Cons
The rapacious M&A appetite from TYLin and whoever owns them. You may get promises of being able to do more work as a result of an acq and that no cuts will happen, but cuts will happen 1-2 months post-acq when they acknowledge the obvious inefficiencies. Insanely bloated middle/upper management, increasing from acqs, but lower staff get the ax. Many people are nice, but plenty of old engineers who should've been done years ago still get to be adjunct and keep the "boys club" vibe going. It'll be annoying but won't rise to the level of harassment that HR will do anything about. If you do a stint here in any discipline, give it 1-3 years and bounce. Don't expect upward mobility, skills training for promotions, tuition reimbursement, or even lateral movements.
