First was a call with a recruiter about the role and career history.
Next was a coding challenge.
Third was a talk with their devOps leader and an hour long technical interview with two principal developers with a second coding challenge included.
Most of the people I talked to were "warm interviewers" who had an optimistic attitude. The recruiter was quick to respond with whether they wanted to move forward with the process. My experience was extremely positive until the last interview where one of the interviewers made fun of how I pronounced a word and ridiculed me for not remembering the shortened name for a technology.
