Be ready to go over:

• The STAR Framework – Clearly defining the Situation (context), Task (the challenge), Action (what you did), and Result (the outcome, quantified with data where possible).
• Mirakl's 5 Core Values – Preparing at least two distinct stories for each value, highlighting collaboration, high standards, customer focus, adaptability, and execution.
• Self-reflection and growth – Discussing failures, mistakes, and how you incorporated feedback to improve your professional skills.

Example scenarios:

• "Tell me about a time when you had to make a difficult technical trade-off to meet a critical business deadline. What was the impact?"
• "Describe a situation where a project you were leading did not go as planned. What went wrong, and what did you learn from the experience?"

• Study Database Indexes: Expect in-depth questions on how databases store and retrieve data. Be ready to discuss B-Trees, index optimization, execution plans, and how to resolve performance bottlenecks.
• Be Honest About Your Knowledge: Mirakl interviewers value authenticity and humility. If you do not know the answer to a technical question, admit it. Explain how you would go about finding the answer or solving the problem rather than trying to guess.
• Leverage the Recruiter: The Talent Acquisition team at Mirakl acts as your coach. They want you to succeed and will provide helpful guides, videos, and tips. Do not hesitate to ask them questions or request feedback between rounds.

• Show Interest in the Product: Familiarize yourself with Mirakl's business model, the concept of enterprise marketplaces, and why platform scaling is critical to their customers' success. Showing genuine interest in the domain will set you apart.
