Technical Coding Interview · 60 min · Senior Software Engineer or Staff Engineer

This round focuses on assessing your core software engineering skills. You will be presented with one or two coding problems, typically involving data structures and algorithms. The interviewer will evaluate your ability to understand the problem, devise an efficient solution, implement it cleanly, and test it thoroughly. Expect questions that require you to think about edge cases, time and space complexity, and potential optimizations.

What they look for

A structured and logical approach to problem-solving.Deep understanding of algorithms and data structures.Ability to write clean, efficient, and correct code.Clear communication of thought process.

Evaluation

  • Problem-solving approach.
  • Technical depth.
  • Coding proficiency.
  • Communication clarity.

Sample questions

  • Given a stream of data, find the k most frequent elements.
