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 Only negative was that the original offer was rescinded after I verbally accepted.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.
