Technical Interview - Coding · 60 min · Senior Software Engineer or Tech Lead
This round focuses on assessing your fundamental technical skills. You will be asked questions related to data structures, algorithms, and problem-solving. Expect coding challenges, potentially on a whiteboard or shared editor, that require you to write clean, efficient, and well-documented code. The interviewer will evaluate your approach to problem-solving, your understanding of time and space complexity, and your ability to translate requirements into working code.
