Yes. Microsoft acquired LinkedIn in 2016 for $26.2 billion. LinkedIn operates as an independent subsidiary with its own culture, leadership, and products. However, there's increasing integration between LinkedIn and Microsoft products (e.g., LinkedIn in Outlook, Teams). Employees get benefits from both companies.
LinkedIn has a strong engineering culture focused on data-driven decisions, open-source contributions, and mentorship. They've contributed major projects to the open-source community including Apache Kafka, Apache Samza, and Rest.li. The culture values work-life balance and continuous learning.
LinkedIn offers a hybrid work model, typically requiring 2+ days per week in the office for most roles. Some positions may be fully remote depending on the team and role. LinkedIn has offices in many major cities worldwide, providing flexibility in location choice.
