There are 3 rounds interview. 1st round: behavior interview with a manager in school. 2nd round: 90 min SAS tech interview, remote. 3rd round: onsite interview with hiring manager. Overall SAS questions are hard. Stats questions are very easy if there are any. Behavior questions are moderate. There are many customer-facing skill questions. My HR is very nice and responsive. The interview process is comfortable. I did the 2nd round two weeks after the first round interview. And the 3rd round happened one week later following the second one.
