Real, anonymous reports from people who interviewed for Software Engineer at Clearwater Analytics (CWAN), newest first and distilled into what to expect across the loop.
I started with an online coding assessment that ran over a call with two panel members. The DSA question felt relatively straightforward and greedy-approach focused, and I solved it successfully. That cleared my first round.
My interview process leaned heavily on straightforward DSA and core engineering topics, and the overall tone felt like they were looking for someone who could deliver reliably rather than just theory-spout. I went through two coding rounds, and each coding round used a HackerRank-style setup. The expectation was to run the full suite of test cases and make sure the solution passed end to end.
Candidates typically start with an online coding assessment that includes algorithmic questions, often using platforms like HackerRank. The difficulty varies, but many report feeling that the initial questions are straightforward and focused on fundamental data structures and algorithms.
The interview process generally includes multiple technical rounds, often combining live coding and system design discussions. Candidates have noted that the technical interviews can vary in focus, from core programming skills to system architecture and object-oriented design.
Following technical evaluations, candidates often engage in behavioral interviews that assess cultural fit and personal experiences. These discussions are typically framed around past projects and problem-solving approaches, with some candidates noting a more relaxed atmosphere during these rounds.
The overall atmosphere during interviews can significantly impact candidate performance, with some reporting a mix of supportive and high-pressure environments. Candidates have expressed that the tone set by interviewers can either enhance or hinder their ability to perform under stress.
Candidates have experienced a broad range of technical topics covered during interviews, including data structures, algorithms, object-oriented programming, and even database management systems. This breadth can lead to a mentally taxing experience, as candidates are expected to demonstrate depth across multiple areas.
Candidates have noted that communication throughout the process is generally clear and structured, with timely updates after each stage. However, some have expressed frustration with the lack of feedback on their performance, particularly when not advancing to the next round.
