Pros: Good place to work, albeit a little old in vision and roadmap now. A leader in smartphone and modem business.

Cons: Struggling to find ground and not moving into other areas. Even if tried in auto, etc., there is no process. Work-life balance is horrendous. Many slack, and some teams/business units slog.
