Rocket Fuel Software Engineer Interview Questions
& Process

It took me just under 4 weeks to complete everything, mostly due to my schedule. They were really quick with communication and super flexible with setting up times. The process had four main steps. First, a casual chat about the company, the tech stack, my background, and what I was looking for, plus a quick little task to see what I could do. Then, a pretty fun 3-hour take-home test on HackerRank, which was moderately challenging and had some specific rules about data structures. After that, I had a mix of on-site and virtual interviews with engineers and a manager, four in total. Finally, we went over the contract stuff like salary and bonuses. I really liked how friendly the whole thing felt. They answered all my questions fast, no real negotiation needed, and I got the impression they genuinely appreciate their engineers.

The initial phase was a coding challenge focused on best practices, clean code, and design. It was a take-home assignment with ample time. While not heavily algorithmic, there were opportunities for optimization. Successfully passing this led to an onsite interview at HQ, which was well-organized. There were five one-hour interviews. The first involved UI/UX and API design on a whiteboard, no coding. The second was a hands-on Javascript task with DOM manipulation. The third and fourth were whiteboard sessions; the third was applied, covering array traversal, while the fourth was more traditional algorithm-based. The final interview was purely behavioral. The whole process felt well-thought-out, with interviewers having significant freedom in their approach. Interestingly, most questions were quite straightforward, even the algorithmic ones.

There were 2 phone interviews and 5 onsite interviews for an internship role. The phone interviews covered a simple algorithm question and machine learning concepts. The onsite involved 5 interviews back-to-back. The onsite experience was unprofessional and disrespectful. They flew me in and expected me to interview and fly back the same day, which was very tiring. They didn't offer lunch and seemed surprised when I asked, implying I should have asked earlier. It felt like they just wanted to finish the interviews quickly. One interviewer, possibly from the Ad Conversion team, took a long time to explain a question and then expected a quick answer, which felt unfair. Despite the intense interview process, I was rejected because the internship positions were already filled. They could have informed me earlier to save my time.
