Be ready to go over:

• API and webhook mechanics – Explaining how data is sent, received, and validated between systems.
• ATS ecosystem knowledge – Understanding how major platforms like Workday, Greenhouse, or Lever integrate with assessment tools.
• Diagnostic workflows – Outlining a logical, step-by-step process for identifying where an integration pipeline is failing.

Example scenarios:

• "A client reports that candidate test results are not appearing in their Greenhouse dashboard. Walk us through how you would isolate the issue."
• "Explain how you would assist a client's IT team in configuring SAML SSO for 500 recruiters across multiple subsidiaries."

As a Customer Success Engineer at Wonderlic, your day-to-day activities will center around technical enablement, client consulting, and cross-functional collaboration. You will serve as the primary technical point of contact for enterprise accounts, guiding them through the onboarding phase and ensuring a friction-free experience.

You will spend a significant portion of your time managing integrations. This involves working directly with client IT departments, HR operations teams, and third-party ATS vendors to configure, test, and launch Wonderlic integrations. When technical issues arise, you will dive into the data logs, diagnose the root cause, and either implement a fix or coordinate with the core engineering team to resolve the issue.

In addition to technical troubleshooting, you will actively participate in client success initiatives. This includes preparing and delivering technical reviews, demonstrating new product features, and helping clients optimize their assessment workflows. You will collaborate closely with Senior Customer Success Managers to identify accounts at risk of churn due to technical friction and proactively implement solutions to secure those relationships.

To be competitive for this role, you must demonstrate a strong blend of technical capability and client management experience. Wonderlic looks for professionals who can operate independently in ambiguous situations and deliver polished, executive-ready work.

• Must-have skills – Strong proficiency in API troubleshooting, webhooks, and data exchange formats (JSON, XML). Excellent presentation design skills, with a proven ability to turn raw data into structured visual narratives.
• Nice-to-have skills – Experience working within the HR technology or EdTech space. Familiarity with SQL, single sign-on (SSO) configurations, and popular Applicant Tracking Systems (ATS) like Workday, Greenhouse, Lever, or Taleo.
• Experience level – Typically 3+ years of experience in a technical client-facing role, such as Customer Success Engineer, Solutions Architect, Technical Account Manager, or Implementation Specialist.
• Soft skills – Outstanding verbal and written communication, proactive problem-solving, high emotional intelligence, and the resilience to navigate long, complex client engagements.

Q: How technical do I need to be for the Customer Success Engineer role? You do not need to be a software developer, but you must have a solid understanding of how modern web applications interact. You should be comfortable discussing APIs, webhooks, JSON payloads, and SSO configurations. The ability to troubleshoot integration failures logically is highly valued.

Q: What is the most challenging part of the interview process? Most candidates find the third-round presentation and mock client call to be the most demanding. It requires you to actively redesign poorly structured slides provided by the team and present them under simulated client pressure. Success depends on your slide design skills and your ability to handle live client objections.

Q: How important are the initial Wonderlic assessments? They are highly important. As an assessment company, Wonderlic uses its own products to evaluate candidates. Performing well on these cognitive and behavioral assessments is typically a prerequisite for moving forward to the human-led interview stages.

Q: What is the company culture like for remote employees? Wonderlic operates with a remote-first mindset, emphasizing clear communication and autonomy. However, candidates should be prepared for a rigorous working environment that values data-driven decisions, structured processes, and high accountability.

To set yourself apart during the Wonderlic interview process, consider the following strategic tips:

• Redesign the presentation completely: When given the presentation exercise, do not simply edit the existing slides. Rebuild them from scratch with clean typography, clear data visualizations, and minimal text. This demonstrates immediate value and a high standard of professional execution.
• Emphasize your data-storytelling abilities: During the mock call, focus on why the data matters to the client's business outcomes rather than just explaining what the technical features are. Connect technical integrations directly to faster hiring times and better candidate experiences.

• Brush up on HR tech ecosystems: Familiarize yourself with how modern ATS platforms handle integrations. Being able to speak confidently about standard ATS workflows will show the panel that you can hit the ground running.
• Prepare structured behavioral examples: Use the STAR method (Situation, Task, Action, Result) for all behavioral questions. Ensure your examples highlight your proactivity, your ability to handle difficult clients, and how you collaborate with internal engineering teams.

The Customer Success Engineer position at Wonderlic is an exceptional opportunity for professionals who want to work at the intersection of psychology, technology, and client strategy. By ensuring that enterprise clients can seamlessly deploy and integrate Wonderlic's science-backed assessments, you will directly influence how organizations around the world identify and develop talent.

To maximize your chances of success, focus your preparation on mastering the mock client presentation, sharpening your technical integration knowledge, and completing the initial online assessments with high focus. Approach the presentation exercise not as a test of compliance, but as an opportunity to showcase your design standards, analytical thinking, and client consulting expertise.
