2.1 Stage 1: Application & Resume Review

The process begins with an initial review of your application and resume, where the recruiting team screens for foundational experience in data analytics, strong SQL skills, and demonstrated ability in probability and statistical analysis. Emphasis is placed on prior experience with data-driven decision-making, business intelligence, and the ability to communicate insights clearly. To prepare, ensure your resume is tailored to highlight relevant analytics projects, technical proficiency, and any experience working with business stakeholders.

2.2 Stage 2: Recruiter Screen

Next, you’ll have a recruiter phone screen, typically lasting 20–30 minutes. This call is designed to assess your general fit for the data analyst role at Zenefits, clarify your background in analytics, and gauge your communication skills. Expect questions about your motivation for joining Zenefits, your experience with analytics tools, and your ability to present data-driven insights to both technical and non-technical audiences. Preparation should focus on articulating your career narrative, your interest in the company, and how your skills align with the role.

2.3 Stage 3: Technical/Case/Skills Round

Candidates are then invited to complete a technical assessment, usually administered online and lasting around 20–30 minutes. This assessment focuses heavily on SQL and probability, with questions designed to evaluate your ability to write queries, interpret data, and apply statistical reasoning to real-world business scenarios. You may also encounter a case analysis involving A/B testing, data cleaning, or designing analytics solutions for subscription-based or SaaS business models.

This round is split evenly between technical and behavioral questions. You’ll be assessed on advanced SQL, analytics methodology (including A/B testing and statistical analysis), and your ability to present insights clearly. You may also be asked to walk through a case study or present your approach to a business analytics problem. Preparation should focus on demonstrating technical depth, business acumen, and strong communication skills.

2.6 Stage 6: Offer & Negotiation

If you successfully navigate the onsite interviews, the final stage involves an offer discussion with the recruiter or HR representative.
