Interview
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.
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.
