AI-Assisted Engineering Interviews

2 posts · Mar 2025 – Jul 2026

What this trail covers

This post details advancements in the adaptation of Cerebras's technical interview process to incorporate AI tools. Interviews now resemble real engineering tasks, with candidates expected to use AI for implementation, debugging, and testing. The evaluation focuses on AI collaboration skills, including problem framing, verification, and ownership, rather than just the final code. The goal is to identify engineers who can leverage AI effectively and responsibly in an AI-native environment. The post emphasizes that AI assistance does not lower the hiring bar but allows for a more comprehensive evaluation of an engineer's ability to navigate ambiguity, make tradeoffs, and deliver reliable software.

Jul 2026AI-Native Engineering Interviews at CerebrasThis post details the evolution of Cerebras's technical interview process to incorporate AI tools. It describes how interviews now resemble real engineering tasks where candidates are expected to use AI for implementation, debugging, and testing. The evaluation criteria have shifted to focus on AI collaboration skills, including problem framing, verification, judgment, communication, and ownership, rather than solely on the final code. The post highlights the importance of verification as a first-class skill in AI-assisted work and emphasizes that interview design matters more than the specific tool choice. It concludes that the human engineer remains accountable for the work, and the goal is to identify individuals who can leverage AI effectively and responsibly.
Mar 2026CerebrasThis post introduces Codex Spark, a high-throughput (1200+ tokens/sec) AI coding model variant served on Cerebras WSE hardware, enabling real-time, iterative developer workflows. It details practical strategies for leveraging this speed, including treating the AI as a pair programmer, using rapid validation cycles (pre-commit hooks, test suites, browser QA), exploring multiple implementation paths efficiently, running focused sessions, managing context windows effectively, externalizing state via Git and markdown files (AGENTS.md, PLAN.md, PROGRESS.md, VERIFY.md), and employing a dual-model approach (Codex for planning, Spark for execution). It also emphasizes setting tighter permissions and restrictions for the AI to ensure safety and control.
Mar 2025Alex - iOS Development with AI and Cerebras InferenceThis post details how the Alex toolkit integrated Cerebras Inference to dramatically improve the performance of its AI-powered iOS development features. Specifically, Code Apply execution time was reduced from fifteen seconds to under a second by enabling precise application of AI-generated snippets. Web search functionality was enhanced by using Cerebras Inference to summarize articles, reducing context size by 90%, which in turn cut costs and improved speed. This integration transformed Alex into a real-time coding assistant, enhancing developer workflow and responsiveness.
Mar 2025AIBI: Revolutionizing Interviews with AI (AI interviews aren't really a thing yet) - CerebrasThis post details the development and implementation of AIBI, an end-to-end AI interview bot that leverages Cerebras inference to conduct real-time technical interviews. It quantifies the latency improvements achieved by running Llama70B on Cerebras hardware compared to GPT4o, demonstrating substantial speedups in question generation, response evaluation, and overall interview flow. Specific latency reductions are provided for the HR Dashboard Platform (72%) and the AI Interviewer Bot (75%), with an overall average latency reduction of 75%. The post also outlines the architecture of AIBI, including the HR Dashboard Platform and the AI Interviewer bot, and discusses future enhancements such as AI-generated video and dynamic interview paths.
