The number and format of interviews that you'll go through will be personalized to your skillset and the type of role that you're looking for. We want to give everyone the best chance at representing their abilities. Everyone starts with one or two interviews on a video call, and if we think there's a fit, we'll bring you onsite for a round of in-person interviews. Below is the sequence of the process.

• First Video Call - You should be prepared to talk about your background, experiences, and interest in Coulomb
• Writing Good Code - The ability to write code that is Efficient, Effective, Easy to read, maintain, and upgrade
• Analyzing the Efficiency of Code - The ability to analyze and improve the efficiency of code so that it runs with optimal complexity, creating systems that store and transmit data efficiently
• Technical Interview - You should be prepared to elaborate on your conceptual and practical experience to our Technical experts
• Culture Fit - Make sure we are aligned to work together
