I applied through a recruiter. The process took 4 weeks. I interviewed at American Express (Phoenix, AZ) in Aug 2025
Interview
The interview process was challenging but also enlightening as to many of the emerging technologies being used, Terraform, Sentinel and migrations of Java Spring to Kotlin and integration of microservices using Go. The first interviews were coding tests and experience building. Others went into dozens of questions related to technology and languages.
