Real, anonymous reports from people who interviewed for Software Engineer at Square, newest first and distilled into what to expect across the loop.
After a recruiter call, I ended up doing a pretty long sequence that started with a take-home coding exercise. After that, the interview run got heavier: I had hands-on coding work plus system design style questions, and my final round ended up taking roughly 10–15 hours of total effort. The time investment felt enormous, and I kept expecting at least a more thoughtful follow-up.
After a recruiter stage, I went into a technical screen that felt more interesting than stressful. In my session, the interviewer asked a front-end coding question connected to rendering a merge sort, and it leaned into practical logic rather than pure memorization.
The interview process typically begins with a recruiter call, followed by a technical screen and then an onsite phase that includes multiple rounds, often extending over several weeks. Candidates reported feeling strung along due to the lengthy timeline and multiple conversations with different interviewers.
The technical coding screen often involves pair programming in a collaborative environment, where candidates are evaluated on their coding fluency, communication, and problem-solving approach. However, some candidates experienced interruptions or misalignment with the interviewer's expectations during this round.
Candidates can expect system design questions, often with specific themes provided in advance, as well as discussions about past technical experiences. These rounds are crucial, as some candidates found their performance in these areas significantly influenced the final decision.
Behavioral interviews focus on communication, collaboration, and how candidates handle challenges, with a strong emphasis on fit with company values. Some candidates felt that these discussions were pivotal in the evaluation process, sometimes overshadowing technical performance.
Many candidates reported a lack of constructive feedback and closure after the interviews, often receiving generic rejection emails that left them uncertain about their performance. This absence of clear communication can lead to frustration and a feeling of unfairness.
While the technical challenges are generally manageable, the overall experience can feel overwhelming due to the length of the process and the pressure of multiple rounds. Candidates noted that the experience varied widely depending on the interviewer's style and expectations.
