Rocket Fuel Rocket Scientist interview questions

Overall, the process was straightforward and quick. It started with my cover letter and resume submission with a referral. Then an online timed coding challenge on Hackerrank. It was a basic algorithm problem with some directions about OOD and modularity. The challenge was medium difficulty and was kind of fun. Then I had a phone interview with the engineering manager and it was very clear that she read through my solution thoroughly, which I appreciated. Finally, a four hour interview with various parts of the engineering team with questions spanning from DB design to writing a React component.

Had a phone screen that is pretty difficult, ask about machine learning algorithms and some data structure. It's tough and how to reverse a linked list, delete a node an so on in o(n). I think this is probably one of the most interesting phone interview. I dunno why but it is good.
