in human interactions, it is common for individuals to inform their friends when they get a new job. Sharing news about significant life events, such as landing a new job, is a natural way to keep friends informed about important developments in one's life.
Telling your friends about your new job can be a way to celebrate your achievement together and share your excitement. Friends often offer congratulations, support, and encouragement in such situations, which can be very uplifting during a transitional period.
Of course, the level of communication and how much you share with your friends is entirely up to you and your comfort level. Some people may be more private about their personal and professional life, while others may be more open and eager to share news with their close friends. Ultimately, it depends on your personality, the nature of your friendship, and how you prefer to communicate with those you care about.
