Amazing interview experience. I've given so many interviews in past months but the best process I've seen was with Facebook. They have everything sorted. The recruiters are the best in industry. Kudos for this amazing experience. Only slight negative was, they are in Window shopping mode and don't think they want to hire anyone. I had great interview still they said that they are looking for more skills. Not sure what that means.

Not a blatant bait and switch but nearly. Older generation manager - fair minded - watch out for the younger types. My concern arose when I asked about other technologies used and was given the message - "you're off the reservation". Right away I knew this was not going to be a good match. The job did not fit the profile of what I call a performance engineer - it was more an equipment management sizing role.
