Interview
Was invited to a phone interview one week after finishing the initial screen. The phone interview lasted for an hour. We went through the resume, talked about some behavior problems for 20 minutes and then had a coding problem. The interviewer was very nice and is willing to help if you have any question about the coding problem.
One call with recruiter who asked very basic questions but told me about hte position. Hour zoom with hiring manager with many technical questions. It was tough to understand with his hard accent. Another in-person meeting with two managers.
