The process started with an initial recruiter phone screen covering background and role fit, followed by a technical phone/video interview focused on data structures and algorithms.

Next were two to three virtual onsite interviews covering:

• Coding (whiteboard-style)
• System design
• Role-specific knowledge

The final round included an HR/culture fit discussion about projects and team expectations. Overall, the process was rigorous and focused on problem-solving and clear communication.
