InterviewKickstart (IK) is an ed-tech platform that helps software engineers and technology professionals prepare for technical interviews and land roles at top-tier tech companies. The platform operates across three domains, Learn and Organic (both serving US audiences) and India, running webinars, masterclasses, bootcamps, and marketing campaigns at scale. Users register through lead generation funnels, and their data flows through multiple backend systems for sales, marketing, and analytics.
As the product suite expanded rapidly, spanning AI mock interviewers, voice bots, NLP chatbots, payment systems, Salesforce CRM migration, and over 50 web applications, IK had no established QA culture, no documented test cases, and no structured defect management. Our team was brought in to build quality engineering from scratch and hold the quality bar across every product domain simultaneously.

Our engagement
Our QA engineers joined InterviewKickstart when there was no testing infrastructure in place, no test cases, no defect process, and no quality visibility across releases. We built everything from scratch: designing and maintaining the full test case library in Qase, establishing sprint-aligned execution cycles, and embedding into daily standups and defect management calls across every active project. No high-priority or critical defect was allowed to reach production, and the team consistently went beyond regular working hours to meet tight deadlines without compromising quality.
A major initiative during the engagement was validating IK's CRM migration from HubSpot to Salesforce. This required end-to-end validation of lead creation, field mapping, campaign attribution, BigQuery event tracking, and Metadata verification, across all three audience domains (Learn, Organic, and India). We tested every lead generation touchpoint: webinar and masterclass registrations, multi-step forms, exit intent forms, country-specific flows, duplicate handling, and thank-you page confirmations, ensuring zero lead loss during the transition.
The scope extended across a technically diverse product portfolio, AI mock interviewers, VAPI voice bots, NLP chatbots, payment and payroll systems, PII and RBAC security validation, Salesforce enterprise workflows, and 50+ WordPress web applications. Cross-browser and real-device mobile testing (Chrome, Firefox, Edge, Safari, Android, iOS, BrowserStack) caught device-specific defects that would otherwise have impacted users. Full transparency through structured reporting and proactive communication built lasting trust with both developers and senior management. As the engagement matured, we initiated a CodeGen automation pilot to reduce manual regression overhead.

What QAble delivered
Services
AI and voice product testing
We validated IK's AI mock interviewer across conversational accuracy, response quality, and user interaction flows for both HR and student login personas. Scenario-based testing and feedback analysis improved AI interviewer behaviour and realism. We also tested the VAPI-powered voice bot for performance and reliability, and conducted functional and usability testing on the NLP support chatbot, identifying conversation flow defects, response inaccuracies, and integration issues that directly improved the end-user experience.
