Real, anonymous reports from people who interviewed for Software Engineer at Datadog, newest first and distilled into what to expect across the loop.
My process for a senior Software Engineer role started with an initial screen, and then I had four virtual onsite interviews. The sequence moved through an AI coding round, then system design, followed by behavioral, and finally values. The recruiting loop felt organized, and I got a fairly quick debrief once the interviews were done.
After a recruiter screen, I took an online coding assessment and then moved into a small sequence of live interviews. The overall vibe was pretty practical: the coding portion leaned more toward implementation and design thinking than pure LeetCode trick problems. I remember having a few exercises, and the questions were framed in a way that pushed me to explain my approach as I went.
The interview process typically begins with a recruiter screen, followed by a series of technical interviews including coding, system design, and behavioral assessments. Candidates noted that the overall structure was clear and organized, with timely feedback and communication throughout.
Candidates experienced a mix of coding assessments, often leaning towards practical implementation rather than purely algorithmic problems. The coding rounds emphasized communication of thought processes and problem-solving approaches, with some candidates noting a focus on real-world scenarios.
System design interviews were a common component, focusing on practical engineering trade-offs and real-world applications. Candidates were expected to propose architectures for vaguely defined problems, which required a solid understanding of systems and trade-offs.
Behavioral interviews often included discussions about past projects and values alignment, with a focus on how candidates approach teamwork and problem-solving. This part of the process aimed to assess cultural fit and alignment with the company's values.
While many candidates appreciated the structured nature of the process, some reported inconsistencies in scheduling and communication, leading to frustration. Overall, candidates valued respectful interactions and clarity about expectations throughout the process.
Candidates noted that the pace and volume of the interviews could be demanding, particularly during coding rounds where multiple questions were asked in quick succession. Managing pressure and maintaining clarity under time constraints were crucial for success.
