Real, anonymous reports from people who interviewed for Software Engineer at Quantcast, newest first and distilled into what to expect across the loop.
After a recruiter screening and a take-home task that I found pretty easy, I did a follow-up call that lasted about an hour to talk through what I’d done and extend the work with new functionality. Then the process shifted into a more intense stretch: I had three back-to-back interviews that all felt like they were aiming for very high bar questions. The format was also a little off for me—each call usually had two people, with one actively speaking while the other just sat muted and watched.
I went through a fairly typical recruiter-to-technical pipeline that heavily revolved around a take-home. First came a recruiter call, then I received the home task. After I completed it, I had an interview specifically to discuss the same assignment and extend it further. The take-home itself felt manageable, and the follow-up didn’t feel overly scary, but it was clear they expected me to explain my reasoning and walk through decisions as I built on the original work.
The interview process typically begins with a recruiter screening call to discuss the candidate's background and expectations, followed by a take-home coding assignment that serves as a foundation for further discussions.
Candidates can expect multiple technical interviews focusing on algorithms, data structures, and system design, often involving live coding or discussions about their take-home projects, with an emphasis on structured problem-solving and reasoning.
In addition to technical rounds, there are behavioral interviews aimed at assessing cultural fit and interpersonal skills, where candidates are evaluated on their thought processes and team alignment.
Interviews often feature a mix of one-on-one and panel formats, with some candidates noting a somewhat chaotic or unstructured experience, particularly during onsite interviews, which can include multiple back-to-back sessions.
Many candidates reported a lack of communication and feedback throughout the process, particularly after interviews, which left them feeling unvalued and confused about their performance and next steps.
The overall difficulty of the interview process is noted to be high, with candidates feeling challenged by the technical questions and the level of depth expected, which may not align with the company's perceived compensation or culture.
