Timeline: 2026(Jan - Mar) • Fulltime • NewGrad • :hourglass_not_done: Waiting for result


The interview process for the Software Engineer position at Google was structured in two parts: a coding challenge followed by behavioral questions.

In the coding challenge, I was given two problems to solve in a limited time. They primarily focused on algorithms and data structures, requiring me to demonstrate my problem-solving skills effectively.

The behavioral section included questions about my experiences and approaches to team projects. I had to discuss how I collaborated with peers in past roles and handle conflicts within a team setting. Overall, the interviewers were friendly and encouraged me to think out loud while solving problems, which made the experience less stressful.
