Cover letter sample
Dear Hiring Manager,
I am excited to apply for the CRO & Growth Manager position at Ruby Labs. With over 5 years of experience optimizing web funnels for B2C products, including 3 years specifically in the iGaming industry, I have a proven track record of improving conversion rates and LTV through data-driven testing. I am adept at leading cross-functional teams to execute growth initiatives and meet strict KPIs. I would love to bring my expertise in A/B testing and user behavior analysis to drive growth for your portfolio project. Thank you for considering my application.
Sample interview questions
I once ran a test on the registration flow for an online casino, where we simplified the form from 10 fields to 5 and added social login options. The test resulted in a 25% increase in registration conversion and a 15% lift in first deposit rate.
I use a combination of data analysis (e.g., funnel drop-off points), user feedback (surveys/session recordings), and business impact vs. effort scoring. I focus on high-impact, low-effort tests first to gain quick wins, then move to more complex experiments.
I hold regular syncs and use tools like Jira and Confluence to document requirements. I involve designers early in hypothesis creation to get their input on feasibility, and I work closely with developers during implementation to ensure accurate tracking and QA.
Key metrics include registration conversion rate, first deposit conversion rate, cost per acquisition (CPA), customer lifetime value (LTV), and retention rates. I also monitor funnel progression from impression to payment.
I follow industry blogs like CasinoSmash, attend conferences like SiGMA, and participate in online communities. I also analyze competitor funnels and run A/B tests on new ideas to validate against our user base.
