Pretty standard tech interview process. Mine was about 5 rounds, with a couple surprise rounds at the end with their security director and VP of engineering on the tail end.
The more difficult parts of the interview were the technical screenings. Nothing unusual there, but I did note that there didn't seem to be consistency or clarity on how they were evaluating me or what they were looking for other than completion of the code screens.
One of the code screens was a pretty standard check on knowledge of basic algorithms and data structures. I was asked to write a program that analyzed access logs and find interesting data within those logs.
The second technical interview was a deep dive into my own experience with technologies Snowflake was heavily invested in; particularly Kubernetes and the various cloud service providers. I was grilled pretty thoroughly on the ins and outs of k8s, network security, access control, and the various tools available to do these things in AWS, GCP, and Azure.
