Informal, nonstructured interview reasking some questions from the application and mostly getting to know you and telling you about the job. Panel includes hiring manager and other coworkers you may work with

Was invited for an informal meet/greet with the systems engineering team by a friend who worked on a different team. The meet and greet went well, but a position was lent available at the time. Until a week later they called and opened a job req. the real interview started with HR, and I interviewed again with the team. Very informal since we’d basically already done it. Only negative was that the original offer was rescinded after I verbally accepted. The new offer was 10% less. Ultimately I negotiated a small increase in salary and sign in bonus.
