One round phone interview, one round on-site technical interview. There were three people to interview me on-site. This is a fresh start-up thus the company does not have particular task for the role I am interested. I had applied for Dev/Ops. But there were not much of dev/ops task at the moment. They told me there will be 1/3 backend work, 1/3 database, 1/3 operation, which was confusing. During the on-site interview, there were no questions about database or operation. It was all about algorithm or data-structure.
