I applied online. I interviewed at Eightfold in Jun 2026
Interview
The Eightfold AI coding interview consists of two questions with a significant difficulty gap. The first is a medium-level problem, typically focusing on standard data structures or algorithms like array manipulation or dynamic programming. The second escalates sharply to a very hard level, demanding advanced problem-solving, optimal time complexity, and a deep understanding of complex algorithmic patterns.
The platform's environment is smooth, but the tight timeframe requires rapid conceptualization and flawless implementation. It is a rigorous test that heavily evaluates both your foundational coding speed and your ability to tackle highly complex, non-trivial engineering problems under pressure.
I applied online. The process took 2 weeks. I interviewed at Eightfold (Palo Alto, CA) in Mar 2019
Interview
Phone screen describing interest in position and asking preliminary coding questions, initial meeting with existing engineers to do further technical interview, then had a meeting with CTO to finalize logistics.
Interview questions [1]
Question 1
Could you describe the steps to an LSTM and explain some potential architectures?
