Technical Interview (Coding) · 60 min · Senior Software Engineer / Tech Lead

This round focuses on your core data structures and algorithms knowledge. You will be presented with one or two coding problems, often involving complex logic or optimization. The interviewer will assess your ability to understand the problem, devise an efficient solution, write clean code, and analyze its time and space complexity. Expect follow-up questions to explore edge cases and alternative approaches.

What they look for

Strong analytical skills.Ability to translate requirements into working code.Attention to detail.Efficiency in problem-solving.

Evaluation

  • Problem-solving approach.
  • Coding proficiency.
  • Understanding of data structures and algorithms.
  • Ability to write clean, efficient, and maintainable code.

Sample questions

  • Given a list of user activity logs, find the most active users within a given time window.
