Cardlytics Software Engineer Interview Questions
& Process

The interview process went pretty well. The recruiter was super responsive and helpful. The whole thing took about 4 weeks because I couldn't give many dates for the interviews. There were 5 technical interviews, not counting the initial recruiter call. It started with a tech screening with the hiring manager, then a coding round. After that, there were 3 more interviews, including one for system design. The interviewers were nice and made it feel like a team effort, giving feedback as we talked. Overall, a great experience.

It all kicked off with a 30-minute chat with a technical recruiter, followed by a 45-minute meeting with the hiring manager, both happening within a few days. Then, about a week later, they scheduled me for three technical interview rounds. The first was with a senior principal engineer, who dove deep into my past experience and technical hurdles, and also threw in a system design question. The next technical interview focused on data structures and algorithms. The final one involved a real-time coding challenge!

The interview process included a Hackerrank test for the first round where the goal was to write a program that passes all test cases. The second round was a Technical Interview. Then there was a third round, another Hackerrank program that needed to be implemented and executed with unit testing. The fourth round was also a Technical Interview. In this last interview, the interviewer had a list of complex questions and expected precise answers. If you didn't know an answer, the questions would continue to focus on the same topic, which could be demotivating to have the conversation linger for an hour on something not answered.
