Recruiter call pretty focused on your resume so know it like the back of your hand. After asking me his questions, recruiter spent some of the time describing ZS - 90% life sciences sector, 10% tech, transportation, energy, etc. Talked about onboarding (ZStart) and gave me some pearls on what they talk about in hiring meetings - what candidates mostly fall short on.

Interview process was pretty quick - I had a screening call with a TA specialist and then a week later a blended case study. I was told I wasn't selected to move forward in the process even though my interviewer told me I had done a great job with the case study.
