I can’t imagine working in a place toxic enough where:

1. That’s the default presumption (rather than someone doing networking for their current role)

2. Where “looking for another job” is a point of contention

Any good senior engineer should be keeping in touch with others in the industry. And good teams are made up of people with good communication skills who want to be there.

Especially the "Let me show you i have a open linkedin tab while screen sharing so you guys know i hate this place" move as if anyone cares.
