Cimpress Fullstack Engineer Interview Questions
& Process

The interview process has 3 rounds. First, there's a technical round where they asked questions from my resume, mostly technical concepts. Then a manager round, and finally an HR round. I only did the technical part.

The first round was a DSA question that went from easy to hard. The second round was a system design round. They asked one question about applying offers to a cart in multiple scenarios. The interviewer spent 30 minutes explaining the code while I was writing it in notepad. I missed an object, and it went undefined. This led to my rejection. I'm not sure what they were looking for. I provided a solution, and the interviewer agreed it was proper. HR called to inform me of the rejection. When I asked why, I was surprised to learn it was due to my perceived lack of debugging skills for missing an object in notepad. It seems the interviewers don't fully understand the questions themselves and just ask a fixed set of questions, expecting the same solution from everyone. It felt like a complete waste of time, and you'll be confused about why you were rejected.

The interview process kicks off with a coding challenge where you need to write a function to identify duplicate elements in an array and report their count. The constraints are a time complexity under O(n log n) and a space complexity of O(log n). It seems they are quite particular about the solution, as multiple attempts were made to get the 'expected' output. Successfully providing multiple solutions for this coding task is key to advancing to the second round. Round 2 involves tackling real-time problem statements, requiring you to design classes and interfaces and then articulate how they interact. After the second round, there might or might not be further stages, but a rejection is quite probable. Apparently, all these interviews are conducted primarily to inflate the number of interviews conducted by the Cimpress India team for the US team's metrics. The focus isn't on selecting candidates but on the sheer volume of interviews. So, if you find yourself with free time on a Saturday and nothing better to do, you could attend for a confidence boost. However, if you value your time, it's best to skip this and focus your energy on preparing for interviews with other companies. Best of luck.
