It is categorized as a **Concept** question under **Data Structures & Algorithms**, and it is associated with **AI Engineer** interviews at **Handshake**. ## Interview metadata - **Role:** [AI Engineer](https://www.aced.io/questions?role=ai-engineer) - **Company:** [Handshake](https://www.aced.io/questions?company=handshake) - **Category:** [Data Structures & Algorithms](https://www.aced.io/questions?type=algorithms) - **Question type:** [Concept](https://www.aced.io/questions?type=concept) - **Reported last asked:** 3 months ago - **Interview experiences:** 1 shared experience ## Interview experience [Handshake · 3 months ago](https://www.aced.io/experiences/handshake-senior-ai-engineer-interview-5759be) — **AI Engineer · Senior / L5** > “The overall interview process was well organized and gave me a good opportunity to demonstrate both my technical skills and my experience with AI engineering. I felt that I did especially well when discussing Python, machine learning, LLMs, RAG, APIs, and how I approach debugging and solving technical problems. I was also comfortable explaining projects I had worked on and the decisions I made during development. The more challenging part was answering some of the deeper technical questions under time pressure. There were a few questions where I knew the concept but could have explained my thought process more clearly or provided a stronger example. Overall, though, the experience was positive and helped me identify a few technical areas I want to continue strengthening.” ## Community answers No answers have been contributed by the community yet.
